CM1624 Datasheet | onsemi

Description The CM1624 is a bination 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/Micro SD 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. Termination resistor value of 40 W is provided on the SDData0, SDData1, SDData2, SDData3, CMD, and CLK lines. Pull- up resistors of 25 k W are included on the SDData0, SDData1, SDData2, SDData3 and CMD lines, as well. These may be configured for devices operating in SD or SPI mode. The TVS diodes provide effective suppression of ESD voltages in excess of 15 k V (contact discharge) per IEC 61000- 4- 2, level 4. The CM1624 is in a 16- pin, Ro HS/WEEE pliant, UDFN 16- pin package. It measures 3.30 x 1.35 x 0.50 mm.
