EMI Filter for T-Flash / MicroSD Interfaces
CM1624
Description The CM1624 is a combination EMI filter and line termination
device with integrated TVS diodes for use on Multimedia Card interfaces. This state−of−the−art device utilizes solid−state, silicon− avalanche technology for superior clamping performance and DC electrical characteristics. The CM1624 has been optimized for protection of T−Flash/MicroSD interfaces in cellular phones and other portable electronics.
The CM1624 consists of six circuits that includes series impedance matching resistors and pull−up resistors as required by the SD specification. TVS diodes are included on each line for ESD protection. An additional TVS diode connection is included for protection of the voltage (Vcc) bus.
