EClamp2122SUSB Downstream Port Filter & TVSFor EMI Filtering and ESD Protection® JEDEC SOT-23 6L packagePb-Free, Halogen Free, RoHS/WEEE Compliant Nominal Dimensions: 2.9 x 2.8mmMolding compound flammability rating: UL 94V-0 Marking: Marking Code + Date Code Packaging: Tape and ReelThe EClamp ®2122S is combination EMI filter and line termination device with integrated TVS diodes for use on USB 2.0 interfaces. This device utilizes solid-state silicon-avalanche technology for superior clamping performance and DC electrical characteristics. Theyhave been optimized for protection of USB inter-protection of USB inter-faces faces in cellular phones and other portable electron-ics.USB line termination is achieved with a series 22Ωresistor on both the D+ and D- USB lines. Theseresistors preserve signal integrity by matching the cable impedance to that of the differential driver. The 15k Ωpull-down resistors complete the termination circuit on each line. They are required by the USB specification to identify the line as a downstream connection. The capacitors are used to bypass high frequency energy to ground and for edge rate control of the USB signals.Integrated TVS diodes provide ESD protection of both (D+ & D-) data lines and the voltage bus (V BUS ). The TVS diodes provide effective suppression of ESD voltages in excess of 25kV (air discharge) and 20kV (contact discharge) per IEC 61000-4-2.The EClamp2122S is in a 6-pin SOT-23 package. The leads are finished with lead-free matte tin.

Pin 1 is connected to the voltage supply line. The input of the D+ line isrouted into pin 2 and out of pin 5. The input of the D- line is connected at pin 3 and the output at pin 4. Pin 6 is connected to ground. The ground connection should be made directly to the ground plane for best results. The path length is kept as short as possible to reduce the effects of parasitic inductance in the board traces.USB Port Design with EClamp2122SThe Universal Serial Bus (USB) specification requires termination and filtering components for proper opera-tion. In addition, an open USB socket is vulnerable to hazardous ESD discharges in excess of 15kV. These discharges can occur on the data lines or the voltage bus. The EClamp2122S is an easily implemented solution designed to meet the termination & EMI filter requirements of the USB specification revision 1.1. It also provides ESD protection to IEC B line termination is achieved with series resistors on both the D+ and D- lines. These resistors preserve signal integrity by matching the cable impedance to that of the differential driver. 15k Ω pull-down resis-tors are used to identify a downstream port. Capaci-tors are used to bypass high frequency energy to ground and for edge rate control of the USB signals.Integrated TVS diodes provide ESD protection of both (D+ & D-) data lines and the voltage bus (V BUS ).General layout guidelines are given below:z Avoid running D+ & D- signal line traces near high speed clock lines or similar signal lines.z Avoid running critical signal lines near board edges.z Place the EClamp2122S near the USB connector to restrict transient coupling.zMinimize the path length between the USB connec-tor and the EClamp2122S.Outline Drawing - SOT-23 6LContact InformationSemtech CorporationProtection Products Division200 Flynn Rd., Camarillo, CA 93012Phone: (805)498-2111 FAX (805)498-3804Tape and Reel SpecificationDevice Orientation in Tapee p a Th t d i W)x aM(,B D1D E FK)X AM(P0P2P)X AM(T W mm8mm2.4)561.(mm1.0+5.1mm0.0-mm0.150.0±01.±57.1mm50.0±5.3mmmm4.21.0±0.4mm1.0±0.4mm50.0±0.2mmmm4.0mm0.8mm3.0+mm1.0-0A0B0Kmm50.0-/+32.3mm50.0-/+71.3mm50.0-/+73.1User Direction of feedYW = 2 - Alphanumeric characters for Date Code。

3、 C5 电容尽量跟 IC 靠近;
4、 C1-C4 电容用于调节相应触摸通道的灵敏度，其电容量值越大灵敏度越低，所感应面板厚度
就越薄。反之，其电容量越小灵敏度越高，所感应面板厚度就越厚。其电容值在 0~50pF.
