CM1624
EMI Filter for T-Flash /
MicroSD Interfaces
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. 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 kV (contact
discharge) per IEC 61000 ? 4 ? 2, level 4. The CM1624 is in a 16 ? pin,
RoHS/WEEE compliant, UDFN 16 ? pin package. It measures 3.30 x
1.35 x 0.50 mm. The leads are spaced at a pitch of 0.4 mm and are
finished with lead ? free NiPd.
