METHOD 3520CCONTINUOUS LIQUID-LIQUID EXTRACTION1.0SCOPE AND APPLICATION1.1This method describes a procedure for isolating organic compounds from aqueous samples. The method also describes concentration techniques suitable for preparing the extract for the appropriate determinative steps described in Sec. 4.3 of Chapter Four.1.2This method is applicable to the isolation and concentration of water-insoluble and slightly soluble organics in preparation for a variety of chromatographic procedures.1.3Method 3520 is designed for extraction solvents with greater density than the sample. Continuous extraction devices are available for extraction solvents that are less dense than the sample. The analyst must demonstrate the effectiveness of any such automatic extraction device before employing it in sample extraction.1.4This method is restricted to use by or under the supervision of trained analysts. Each analyst must demonstrate the ability to generate acceptable results with this method.2.0SUMMARY OF METHOD2.1 A measured volume of sample, usually 1 liter, is placed into a continuous liquid-liquid extractor, adjusted, if necessary, to a specific pH (see Table 1), and extracted with organic solvent for 18 - 24 hours.2.2The extract is dried, concentrated (if necessary), and, as necessary, exchanged into a solvent compatible with the cleanup or determinative method being employed (see Table 1 for appropriate exchange solvents).3.0INTERFERENCES3.1Refer to Method 3500.3.2The decomposition of some analytes has been demonstrated under basic extraction conditions required to separate analytes. Organochlorine pesticides may dechlorinate, phthalate esters may exchange, and phenols may react to form tannates. These reactions increase with increasing pH, and are decreased by the shorter reaction times available in Method 3510. Method 3510 is preferred over Method 3520 for the analysis of these classes of compounds. However, the recovery of phenols may be optimized by using Method 3520 and performing the initial extraction at the acid pH.4.0APPARATUS AND MATERIALS4.1Continuous liquid-liquid extractor - Equipped with polytetrafluoroethylene (PTFE) or glass connecting joints and stopcocks requiring no lubrication (Kontes 584200-0000, 584500-0000, 583250-0000, or equivalent).CD-ROM3520C - 1Revision 3December 19964.2Drying column - 20 mm ID Pyrex® chromatographic column with Pyrex® glass wool at bottom and a PTFE stopcock.NOTE:Fritted glass discs are difficult to decontaminate after highly contaminated extracts have been passed through. Columns without frits may be purchased.Use a small pad of Pyrex® glass wool to retain the adsorbent. Prewash theglass wool pad with 50 mL of acetone followed by 50 mL of elution solvent priorto packing the column with adsorbent.4.3Kuderna-Danish (K-D) apparatus4.3.1Concentrator tube - 10-mL graduated (Kontes K-570050-1025 or equivalent).A ground glass stopper is used to prevent evaporation of extracts.4.3.2Evaporation flask - 500-mL (Kontes K-570001-500 or equivalent).

Unless otherwise indicated, it isintended that all reagents shall conform to the specifications of the Committee on AnalyticalReagents of the American Chemical Society, where such specifications are available. Other gradesmay be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit itsuse without lessening the accuracy of the determination. Reagents should be stored in glass toprevent the leaching of contaminants from plastic containers.5.2Organic-free reagent water - All references to water in this method refer to organic-freereagent water, as defined in Chapter One.5.3Sodium hydroxide solution (10N), NaOH. Dissolve 40 g NaOH in organic-free reagentwater and dilute to 100 mL. Other concentrations of hydroxide solutions may be used to adjustsample pH, provided that the volume added does not appreciably change (e.g., <1%) the totalsample volume.5.4Sodium sulfate (granular, anhydrous), Na SO . Purify by heating at 400E C for 4 hours24in a shallow tray, or by precleaning the sodium sulfate with methylene chloride. If the sodium sulfateis precleaned with methylene chloride, a method blank must be analyzed, demonstrating that thereis no interference from the sodium sulfate.5.5Sulfuric acid solution (1:1 v/v), H SO . Slowly add 50 mL of H SO (sp. gr. 1.84) to 5024 24mL of organic-free reagent water. Other concentrations of acid solutions may be used to adjustsample pH, provided that the volume added does not appreciably change (e.g., <1%) the totalsample volume.5.6Extraction/exchange solvents - All solvents must be pesticide quality or equivalent.5.6.1Methylene chloride, CH Cl , boiling point 39E C. 225.6.2Hexane, C H , boiling point 68.7E C.6145.6.32-Propanol, CH CH(OH)CH , boiling point 82.3E C. 335.6.4Cyclohexane, C H , boiling point 80.7E C. 6125.6.5Acetonitrile, CH CN, boiling point 81.6E C.36.0SAMPLE COLLECTION, PRESERVATION, AND HANDLINGSee the introductory material to this chapter, Organic Analytes, Sec. 4.1.7.0PROCEDURE7.1Using a 1-liter graduated cylinder, measure 1 liter (nominal) of sample. Alternatively, ifthe entire contents of sample bottle are to be extracted, mark the level of sample on the outside ofthe bottle. If high concentrations are anticipated, a smaller sample volume may be taken and dilutedto 1-L with organic-free reagent water. It is recommended that if high analyte concentrations areanticipated, samples should be collected in smaller sample bottles and the whole sample used.7.2Pipet 1.0 mL of the surrogate spiking solution into each sample in the graduated cylinder (or sample bottle) and mix well. (See Method 3500 and the determinative method to be used for details on the surrogate standard solution and matrix spiking solution).7.2.1For the sample in each batch (see Chapter One) selected for use as a matrixspike sample, add 1.0 mL of the matrix spiking standard.7.2.2If Method 3640, Gel-Permeation Cleanup, is to be employed, add twice thevolume of the surrogate spiking solution and the matrix spiking standard, since half of the extract is not recovered from the GPC apparatus. (Alternatively, use 1.0 mL of the spiking solutions and concentrate the final extract to half the normal volume, e.g., 0.5 mL instead of1.0 mL).7.3Check the pH of the sample with wide-range pH paper and adjust the pH, if necessary, to the pH indicated in Table 1, using 1:1 (v/v) sulfuric acid or 10 N sodium hydroxide. Lower concentrations of acid or base solution may be employed, provided that they do not result in a significant change (<1%) in the volume of sample extracted (see Secs. 5.3 and 5.5).7.4Add 300 - 500 mL of methylene chloride to the distilling flask of the extractor. Add several boiling chips to the flask.7.5Quantitatively transfer the sample from the graduated cylinder (or sample bottle) to the extractor. Use a small volume of methylene chloride to rinse the cylinder (or bottle) and transfer this rinse solvent to the extractor. Add organic-free reagent water to the extractor, if needed, to ensure proper operation and extract for 18-24 hours. If the sample was transferred directly from the sample bottle, refill the bottle to the mark made in Sec. 7.1 with water and then measure the volume of sample that was in the bottle.7.6Allow the extractor to cool, then detach the boiling flask. If extraction at a secondary pH is not required (see Table 1), the extract is dried and concentrated using one of the techniques described in Secs. 7.10 - 7.11.7.7If a pH adjustment and second extraction is required (see Table 1), carefully, while stirring, adjust the pH of the aqueous phase to the second pH indicated in Table 1. If the extracts are to be analyzed separately (see Sec. 7.8), attach a clean distilling flask containing 500 mL of methylene chloride to the continuous extractor. Extract for 18-24 hours, allow to cool, and detach the distilling flask. If the extracts are not to be analyzed separately, then the distilling flask and solvent need not be changed and may be used for the second pH extraction.7.8If performing GC/MS analysis (Method 8270), the acid/neutral and base extracts may be combined prior to concentration. However, in some situations, separate concentration and analysis of the acid/neutral and base extracts may be preferable (e.g., if for regulatory purposes the presence or absence of specific acid/neutral and base compounds at low concentrations must be determined, separate extract analyses may be warranted).7.9Perform concentration (if necessary) using the Kuderna-Danish technique (Secs. 7.10.1 through 7.10.6).7.10K-D technique7.10.1Assemble a Kuderna-Danish (K-D) concentrator (Sec. 4.3) by attaching a 10-mLconcentrator tube to a 500-mL evaporation flask.CD-ROM3520C - 4Revision 3December 19967.10.2Attach the solvent vapor recovery glassware (condenser and collection device)(Sec. 4.4) to the Snyder column of the K-D apparatus following manufacturer's instructions.7.10.3Dry the extract by passing it through a drying column containing about 10 cm ofanhydrous sodium sulfate. Collect the dried extract in a K-D concentrator. Rinse the Erlenmeyer flask, which contained the solvent extract, with 20 - 30 mL of methylene chloride and add it to the column to complete the quantitative transfer.7.10.4Add one or two clean boiling chips to the flask and attach a three-ball Snydercolumn. Prewet the Snyder column by adding about 1 mL of methylene chloride to the top of the column. Place the K-D apparatus on a hot water bath (15 - 20E C above the boiling point of the solvent) so that the concentrator tube is partially immersed in the hot water and the entire lower rounded surface of the flask is bathed with hot vapor. Adjust the vertical position of the apparatus and the water temperature, as required, to complete the concentration in 10 -20 minutes. At the proper rate of distillation the balls of the column will actively chatter, butthe chambers will not flood. When the apparent volume of liquid reaches 1 mL, remove the K-D apparatus from the water bath and allow it to drain and cool for at least 10 minutes.7.10.5If a solvent exchange is required (as indicated in Table 1), momentarily removethe Snyder column, add 50 mL of the exchange solvent, a new boiling chip, and reattach the Snyder column. Alternatively, pour the exchange solvent into the top of the Snyder column while the concentrator remains on the water bath in Sec. 7.10.4. Concentrate the extract, as described in Sec. 7.10.4, raising the temperature of the water bath, if necessary, to maintain proper distillation.7.10.6Remove the Snyder column and rinse the flask and its lower joints into theconcentrator tube with 1 - 2 mL of methylene chloride or exchange solvent. If sulfur crystals are a problem, proceed to Method 3660 for cleanup. The extract may be further concentrated by using the techniques outlined in Sec. 7.11 or adjusted to 10.0 mL with the solvent last used.7.11If further concentration is indicated in Table 1, either the micro-Snyder column technique (7.11.1) or nitrogen blowdown technique (7.11.2) is used to adjust the extract to the final volume required.7.11.1Micro-Snyder column techniqueAdd another one or two clean boiling chips to the concentrator tube and attacha two-ball micro-Snyder column. Prewet the column by adding 0.5 mL of methylenechloride or exchange solvent to the top of the column. Place the K-D apparatus in a hotwater bath so that the concentrator tube is partially immersed in the hot water. Adjustthe vertical position of the apparatus and the water temperature, as required, to completethe concentration in 5 - 10 minutes. At the proper rate of distillation the balls of thecolumn will actively chatter, but the chambers will not flood. When the apparent volumeof liquid reaches 0.5 mL, remove the K-D apparatus from the water bath and allow it todrain and cool for at least 10 minutes. Remove the Snyder column, rinse the flask andits lower joints into the concentrator tube with 0.2 mL of methylene chloride or theexchange solvent, and adjust the final volume as indicated in Table 1, with solvent. CD-ROM3520C - 5Revision 3December 19967.11.2Nitrogen blowdown technique7.11.2.1Place the concentrator tube in a warm bath (35E C) and evaporate thesolvent to the final volume indicated in Table 1, using a gentle stream of clean, drynitrogen (filtered through a column of activated carbon).CAUTION:New plastic tubing must not be used between the carbon trap andthe sample, since it may introduce contaminants.7.11.2.2The internal wall of the tube must be rinsed several times withmethylene chloride or appropriate solvent during the operation. During evaporation, thetube must be positioned to avoid water condensation (i.e., the solvent level should bebelow the level of the water bath). Under normal procedures, the extract must not beallowed to become dry.CAUTION:When the volume of solvent is reduced below 1 mL, semivolatileanalytes may be lost.7.12The extract may now be analyzed for the target analytes using the appropriate determinative technique(s) (see Sec. 4.3 of this chapter). If analysis of the extract will not be performed immediately, stopper the concentrator tube and store refrigerated. If the extract will be stored longer than 2 days it should be transferred to a vial with a PTFE-lined screw-cap or crimp top, and labeled appropriately.8.0QUALITY CONTROL8.1Any reagent blanks, matrix spikes, or replicate samples should be subjected to exactly the same analytical procedures as those used on actual samples.8.2Refer to Chapter One for specific quality control procedures and Method 3500 for extraction and sample-preparation procedures.9.0METHOD PERFORMANCERefer to the determinative methods for performance data.10.0REFERENCESNone.CD-ROM3520C - 6Revision 3December 1996CD-ROM 3520C - 8Revision 3December 1996METHOD 3520CCONTINUOUS LIQUID-LIQUID EXTRACTION。

USPORT transceiver will operate in full-speed electrical signaling when GL3520-22 is plugged into a 1.1 host/hub. USPORT transceiver will operate in high-speed electrical signaling when GL3520-22 is plugged into a 2.0 host/hub.4.2.2 USB 3.0 USPORT TransceiverUSB 3.0 USPORT (upstream port) transceiver is the analog circuit that has elastic buffer and supports receiver detection, data serialization and de-serialization. Besides, it has PIPE interface with SuperSpeed Link Layer4.2.3 PLL (Phase Lock Loop)PLL generates the clock sources for the whole chip. The generated clocks are proven quite accurate that help in generating high speed signal without jitter.4.2.4 RegulatorGL3520-22 build in internal regulator converts 5V input to 3.3V output.4.2.5 SPI EngineSPI engine is to move code from external flash to the internal RAM.4.2.6 RAM/ROM/CPUThe micro-processor unit of GL3520-22 is an 8-bit RISC processor with 16K-byte ROM and 256-bytes RAM. It operates at 12MIPS of 12 MHz clock( maximum) to decode the USB command issued from host and then prepares the data to respond to the host.4.2.7 UTMI (USB 2.0 Transceiver Microcell Interface)UTMI handles the low level USB protocol and signaling. It’s designed based on the Intel’s UTMI specification 1.01. The major functions of UTMI logic are to handle the data and clock recovery, NRZI encoding/decoding, Bit stuffing /de-stuffing, supporting USB 2.0 test modes, and serial/parallel conversion.4.2.8 SIE (Serial Interface Engine)SIE handles the USB protocol defined in chapter 8 of USB specification revision 2.0. It co-works with μC to play the role of the hub kernel. The main functions of SIE include the state machine of USB protocol flow, CRC check, PID error check, and timeout check. Unlike USB 1.1, bit stuffing/de-stuffing is implemented in UTMI, not in SIE.4.2.9 Control/Status RegisterControl/Status register is the interface register between hardware and firmware. This register contains the information necessary to control endpoint0 and endpoint1 pipelines. Through the firmware based architecture, GL3520-22 possesses higher flexibility to control the USB protocol easily and correctly.4.2.10 Power Management EngineThe power management of GL3520-22 is compliant with USB 3.0 specification. When operates in SuperSpeed mode, GL3520-22 supports U0, U1, U2 and U3 power states. U0 is the functional state. U1 and U2 are lower power states compared to U0. U1 is a low power state with fast exit to U0; U2 is a low power state which saves more power than U1, with slower exit to U0. U3 is suspend state, which is the most power-saving state, with tens of milliseconds exit to U0. Unlike USB 2.0, SuperSpeed packet traffic is unicast rather than broadcast. Packet only travels the direct path in-between host and the target device.SuperSpeed traffic will not reach an unrelated device. When enabled for U1/U2 entry, and there is no pending traffic within comparable exit latency, GL3520-22 will initiate U1/U2 entry to save the power. On the other hand, the link partner of GL3520-22 may also initiate U1/U2 entry. In this case, GL3520-22 will accept or reject low power state entry according to its internal condition.4.2.11 Router/Aggregator EngineRouter/Aggregator Engine implements the control logic defined in Ch10 of USB3.0 specification. Router/Aggregator Engine use smart method for route packet to device or aggregate packet to host.4.2.12 REPEATERRepeater logic implements the control logic defined in section 11.4 and section 11.7 of USB specification revision 2.0. REPEATER controls the traffic flow when upstream port and downstream port are signaling in the same speed. In addition, REPEATER will generate internal resume signal whenever a wakeup event is issued under the situation that hub is globally suspended.4.2.13 TTTT(Transaction Translator) implements the control logic defined in section 11.14 ~ 11.22 of USB specification revision 2.0. TT basically handles the unbalanced traffic speed between the USPORT (operating in HS) and DSPORTS (operating in FS/LS) of hub. GL3520-22 adopts multiple TT architecture to provide the most performance effective solution. Multiple TT provides control logics for each downstream port respectively.4.2.13.1 Connected to 1.1 Host/HubIf an USB 2.0 hub is connected to the downstream port of an USB 1.1 host/hub, it will operate in USB 1.1 mode. For an USB 1.1 hub, both upstream direction traffic and downstream direction traffic are passing through REPEATER. That is, the REPEATER/TT routing logic will route the traffic channel to the REPEATER.Figure 4.2 - Operating in USB 1.1 Schemes4.2.13.2 Connected to USB 2.0 Host/HubIf an USB 2.0 hub is connected to an USB 2.0 host/hub, it will operate in USB 2.0 mode. The upstream port signaling is in high speed with bandwidth of 480 Mbps under this environment. The traffic channel will then be routed to the REPEATER when the device connected to the downstream port is signaling also in high speed. On the other hand, the traffic channel will then be routed to TT when the device connected to the downstream port is signaling in full/low speed.Figure 4.3 - Operating in USB 2.0 Schemes4.2.14 CDP Control LogicCDP (charging downstream port) control logic implements the logic defined in USB Battery charging specification revision 1.2. The major function of it is to control DSPORT Transceiver to make handshake with a portable device which is compliant with USB Battery charging spec rev1.2 as well. After recognizing charging detection each other, portable device will draw up to 1.5A from VBUS to fast charge its battery. 4.2.15 USB 3.0/USB 2.0 DSPORT TransceiverDSPORT transceiver is the analog circuit that supports high-speed, full-speed, and low-speed electrical characteristics. In addition, each DSPORT transceiver accurately controls its own squelch level to detect the detachment and attachment of devices.4.3 Configuration and I/O Settings 4.3.1 RESET SettingGL3520-22’s power on reset can either be triggered by external reset or internal power good reset circuit. The external reset pin, RESETJ, is connected to upstream port Vbus (5V) to sense the USB plug / unplug or 5V voltage drop. The reset trigger voltage can be set by adjusting the value of resistor R1 and R2 (Suggested value refers to schematics) GL3520-22’s internal reset is designed to monitor silicon’s internal core power (1.2V) and initiate reset when unstable power event occurs. The power on sequence will start after the power good voltage has been met, and the reset will be released after approximately 40 μS after power good. GL3520-22’s reset circuit as depicted in the picture.GlobalReset#V BUS“Figure 4.4 - Power on Reset DiagramTo fully control the reset process of GL3520-22, we suggest the reset time applied in the external reset circuit should longer than that of the internal reset circuit. Timing of POR is illustrated as below figure.External resetVCC(3.3V) (1.2V)Figure 4.5 - Power on Sequence of GL3520-224.3.2 PGANG SettingTo save pin count, GL3520-22 uses the same pin to decide individual/gang mode as well as to output the suspend flag. The individual/gang mode is decided within 21us after power on reset. Then, about 50ms later, this pin is changed to output mode. GL3520-22 outputs the suspend flag once it is globally suspended. For individual mode, a pull low resister greater than 100KΩshould be placed. For gang mode, a greater than 100KΩpull high resister should be placed. In figure 4.7, we also depict the suspend LED indicator schematics. It should be noticed that the polarity of LED must be followed, otherwise the suspend current will be over spec limitation (2.5mA).Figure 4.6 - Timing of PGANG StrappingIndividualModeFigure 4.7 - GANG Mode Setting4.3.3 SELF/BUS Power Setting4.3.4 LED ConnectionsGL3520-22 controls the LED lighting according to the flow defined in section 11.5.3 of Universal Serial Bus Specification Revision2.0. Both manual mode and Automatic mode are supported in GL3520-22. WhenDGNDFigure 4.9 - LED Connection4.3.5 Power SwitchGL3520 supports low active power switch. Please refer to the reference schematic for power switch control.4.3.6 Port Number ConfigurationNumber of downstream port can be configured as 4/3/2 ports by firmware configuration, EEPROM, and pin strapping. Please refer to Genesys USB 3.0 Hub FW ISP Tool User Guide for the detailed setting information.4.3.7 Non-removable Port ConfigurationFor compound application or embedded system, downstream ports that always connect inside the system can be set as non-removable by firmware configuration, EEPROM, and pin strapping. Please refer to Genesys USB 3.0 Hub FW ISP Tool User Guide for the detailed setting information.CHAPTER 5 BATTERY CHARGING SPECIFICATION REV.1.2 SUPPORT5.1 BackgroundThe USB ports on personal computers are convenient places for portable devices to draw current for charging their batteries. This convenience has led to the creation of dedicated chargers that simply expose a USB standard-A receptacle. This allows portable devices to use the same USB cable to charge from either a PC or from a dedicated charger.If a portable device is attached to a USB host or hub, then the USB 2.0 specification requires that after connecting, a portable device must draw less than:∙ 2.5 mA average if the bus is suspended∙100 mA maximum if bus is not suspended and not configured∙500 mA maximum if bus is not suspended and configured for 500 mAIf a portable device is attached to a charging host or hub, it is allowed to draw a current up to 1.5A, regardless of suspend. In order for a portable device to determine how much current it is allowed to draw from an upstream USB port, the USB-IF Battery Charging specification defines the mechanisms that allow the portable device to distinguish between a USB standard host, hub or a USB charging host. Since portable devices can be attached to USB charging ports from various manufactures, it is important that all USB charging ports behave the same way. This specification also defines the requirements for a USB chargers and charging downstream ports.5.2 Standard Downstream Port (SDP)GL3520-22 complies with Battery Charging Specification rev1.2, which defines three charging ports: SDP, CDP and DCP. The SDP is a standard USB port which can transfer data and provide maximum 500mA current.5.3 Charging Downstream Port (CDP)GL3520-22 supports battery charging detection, turning its downstream port from a standard downstream port (SDP) into charging downstream port (CDP). GL3520-22 will make physical layer handshaking when a portable device that complies with BC rev1.2 attaches to its downstream port. After physical layer handshaking, a portable device is allowed to draw more current up to 1.5A.Once the charging downstream port of GL3520-22 is enabled, it will monitor the V DP_SRC on D+ line anytime. When a portable device, which is compliant with BC rev1.2, is attached to the downstream port, it will drive V DP_SRC on D+ line to initiate the handshake with charging downstream port. GL3520-22 will response on its D- line by V DM_SRC and keep in a certain period of time and voltage level. The portable device will accept this handshaking on its D- line in correct timing period and voltage level, and then turns off its V DP_SRC on D+ line. GL3520-22 will recognize that charging negotiation is finished by counting time between the portable device turning on and off its V DP_SRC. After that, the portable device can start to draw more current from VBUS to charge its battery more rapidly. It can draw current up to 1.5A.If there is no response from D- line, the portable device will recognize that it is attached to a standard downstream port, not a charging port.5.4 Dedicated Charging Port (DCP)GL3520-22 also supports dedicated charging port, which is a downstream port on a device that outputs power through a USB connector, but it is not capable of enumerating a downstream device. With the adequate system circuit design, GL3520-22 will turn its downstream port from a standard downstream port (SDP) into dedicated charging port (DCP), i.e short the D+ line to the D- line, to let the portable device draws current up to 1.5A. Please refer to the USB 3.0 Hub Design Guide document for the detailed information.5.5 ACA-DockAn ACA-Dock is a docking station that has one upstream port, and zero or more downstream ports. The upstream port can be attached to a portable device (PD), and is capable of sourcing ICDP to the PD, which means that the upstream port can charge and have data communication with the PD at the same time. Please refer to Battery Charging Spec v1.2 for more details.5.6 Apple and Samsung DevicesExcept BC rev1.2-complied portable devices, GL3520-22 also supports the fast charging of Apple and Samsung devices.- Apple: iPhone, iPad series.- Samsung: Galaxy Tab series, Galaxy Mobile Phones series.5.7 Port Numbers of Charging Downstream Port ConfigurationNumber of charging downstream port can be configured as 1/2/3/4 ports by firmware configuration. Please refer to the Genesys USB 3.0 Hub FW ISP Tool User Guide document for the detailed setting information.CHAPTER 6 ELECTRICAL CHARACTERISTICS 6.1 Maximum RatingsTable 6.1 - Maximum Ratings*Please refer to the reference design schematic.6.2 Operating RangesTable 6.2 - Operating Ranges6.3 DC Characteristics6.3.1 DC Characteristics except USB SignalsTable 6.3 - DC Characteristics except USB Signals* Schmitt trigger pads are VBUS, RESET6.3.2 USB 2.0 Interface DC CharacteristicsThe GL3520-22 conforms to DC characteristics for Universal Serial Bus specification rev. 2.0. Please refer to this specification for more information.6.3.3 USB 3.0 Interface DC CharacteristicsThe GL3520-22 conforms to DC characteristics for Universal Serial Bus specification rev.3.0. Please refer to this specification for more information.6.4 Power ConsumptionTest result represents silicon level operating current, without considering additional powerconsumption contributed by external over-current protection circuit such as power switch orpolyfuse. The power consumption measured by 5V is based on Genesys’ evaluation board. It maybe diverse with regulator power transfer efficiency and firmware configurations.6.5 On-Chip Power RegulatorGL3520-22 requires 3.3V source power for normal operation of internal core logic and USB physical layer (PHY). The integrated low-drop power regulator converts 5V power input from USB cable (Vbus) to 3.3V voltage for silicon power source. The 3.3V power output is guaranteed by an internal voltage reference circuit to prevent unstable 5V power compromise USB data integrity. The regulator’s maximum current loading is 250mA, which provides enough tolerance for normal GL3520-22 operation (below 100mA).On-chip Power Regulator Features: ● 5V to 3.3V low-drop power regulator● 250mA maximum output driving capability●Provide stable 3.3V output when Vin = 3.4V~5.5V ● 125uA maximum quiescent current (typical 80uA).Figure 6.1 - Vin(V5) vs Vout(V33)**Note: Measured environment: Ambient temperature = 25℃ / Current Loading = 250mA6.6 External ClockXOUT: 25MHz crystal oscillator output.

抗雾霾神器车载净化器车载测试报告
近日，雾霾问题再度成为公众关注热点。

雾霾中的主要成分PM2.5，这种
可吸入的微粒对健康造成威胁。

对于汽车的驾乘者来说，车内还有各种化学污
染物，如甲醛、甲苯，此时，PM2.5又会成为它们的载体，附着着各种有害物
质被吸入人体，产生更为严重的危害。

车载空气净化器市场再度火爆，而鱼龙混杂的市场销售，品种繁多的净化技术，令消费者应接不暇，陷入被动消费境地。

鉴于此，小编对市场上5款主流
品牌车载空气净化器：沃讯V9，飞利浦Compact200，3M-PN3880.夏普IG- BC2S-B和慑力H3S进行对比测试，为各位车主在选购车载空气净化器时提供
权威参考。

净化能力是关键
对PM2.5细微颗粒、甲醛/甲苯、TVOC等有害物质的实际净化效率是车载
空气净化器的核心功能，对这些有害物质的实际净化效率，也是鉴定一款车载
空气净化器是否有用的最重要指标。

此次测试过程中特别委托了上海市环保产
品质量监督检验总站进行了PM2.5细微颗粒、甲醛/甲苯、TVOC等有害物质
的实际净化效率进行检测。

以上检测参照GB/T18883-2002标准检测环境为1立方米。

在化学污染物去除率方面，飞利浦Compact200的成绩可以说是遥遥领先，
甲醛甲苯的净化率均超过其他品牌，TVOC的去除率更是超过了99%;同样作为国际品牌的3M，甲醛的净化效率为86%，而另外的3款产品基本对于化学污
染没有明显的去除效果。

在PM2.5颗粒净化效率方面，飞利浦Compact200和沃讯V9相比不相上下，3M产品虽然去除率也达到了92%，但是比起>99%的净化效能，还是稍显欠缺。

移动通信技术的发展，为物联网技术提供了强有力的支持，在交通运输行业催生了车联网这一概念。

车联网概念引申自物联网（Internet of Things，IoT）。

行业背景不同，对车联网的定义也不相同。

传统的车联网定义是指装载在车辆上的电子标签，通过无线射频等识别技术实现在信息网络平台上，对所有车辆的属性信息和静、动态信息进行提取和有效利用。

根据不同的功能需求，对所有车辆的运行状态，进行有效的监管并提供综合服务的系统。

车载视频监控是车联网领域的一个重要研究课题，它能方便用户实时、直观地监控车辆安全情况[1]。

为了更有效地对车辆情况进行监管，本设计使用Hi3520D作为车载终端核心芯片，基于Linux嵌入式进行程序设计，实现采集、显示、存储视频数据功能，将车载终端作为流媒体服务器，供远程视频监控软件查看视频终端内的视频文件。
