Datasheet Summary
Data Port EMI Filter Array with ESD Protection
Description The CM1454 is an EMI filter array with ESD protection in a CSP form factor for the data port of a mobile handset. The CM1454- 08 is configured in an 8 channel format and bines both resistor- capacitor (R- C) and inductor- capacitor (L- C) filters in the chip. There are five C- R- C filters with ponent values of 30 pF
- 100 W
- 30 pF which are used for the microphone and data ports. There are also three C- L- C filters with values of 80 pF
- 3 nH
- 80 pF which are designed for the stereo speaker port.
The CM1454’s C- RC filters have a cut- off frequency of 60 MHz and an attenuation of better than 35 dB over the 800 MHz to 2.7...
