Features
The EClampTM3202A is a low pass filter array with integrated TVS diodes for ESD protection. It is de- signed to provide bidirectional filtering of EMI/RFI signals and electrostatic discharge (ESD) protection in portable electronic equipment. This state-of-the-art device utilizes solid-state silicon-avalanche technology for superior clamping performance and DC electrical characteristics. They have been optimized for use on a microphone port in cellular phones and other protable electronics. The EClamp3202A effectively replaces 10 discrete components in a small SC-89 package to provide ESD protection and EMI filtering. Each device requires less than 2.9mm 2 of PCB area with a low profile of only 0.60mm. This small package will protect and filter up to two lines. This small outline makes the device especially well suited for portable applications. The TVS diodes are bidirectional for supporting bipolar audio signals without distortion. The TVS diodes provide effective suppression of ESD voltages in excess of ±15kV (air discharge) and ±8kV (contact discharge) per IEC 61000-4-2, level 4. The device has very low inser- tion loss in the pass band and high attenuation at fre- quencies ranging from 800MHz to 3GHz. Each line fea- tures two stages of TVS diode protection. They feature large cross-sectional area junctions for conducting high transient currents. They offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device deg- radation.

4 2006 Semtech Corp. www.semtech.com PRELIMINARYPROTECTION PRODUCTS EClamp3202A LOW PASS FILTER Layout Examples Equivalent Circuit Diagram (Each Line) Applications Information Device Connection Options The EClamp3202A provides EMI filtering and ESD protection in a small SC-89 package for speaker port applications. The equivalent circuit diagram is shown below. The layout of the device is designed such that the data lines can be routed through the device. The first line pair enters at pins 1 and exits at pins 6. The second line pair enters at pins 3 and exits at pins 4. The device is symmetrical so the above connections may be reversed. Layout examples are shown to the right. Option 1 Option 2 Circuit Board Layout Recommendations for Suppres- sion of ESD. Good circuit board layout is critical for the suppression of ESD induced transients. The following guidelines are recommended: z Place the TVS near the input terminals or connec- tors to restrict transient coupling. z Minimize the path length between the TVS and the protected line. z Minimize all conductive loops including power and ground loops. z The ESD transient return path to ground should be kept as short as possible. z Never run critical signals near board edges. z Use ground planes whenever possible. niPn oitacifitnedI 1) enohporciMmorF(nI1eniL 6) tiucriCoiduAoT(tuO1eniL 3) enohporciMmorF(nI2eniL 4) tiucriCoiduAoT(tuO2eniL 5,2d nuorG EClamp- Audio Codec 3202A Micro- phone 3EClamp- Audio Codec3202AMicro- phone niPn oitacifitnedI 6) enohporciMmorF(nI1eniL 1) tiucriCoiduAoT(tuO1eniL 4) enohporciMmorF(nI2eniL 3) tiucriCoiduAoT(tuO2eniL 5,2d nuorG
