CM1454 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.
