CM1454-08CP

带ESD保护的数据端口的EMI滤波器阵列 Data Port EMI Filter Array with ESD Protection

Product 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 combines both resistor capacitor R-C and inductor-capacitor L-C filters in the chip. There are five C-R-C filters with component values of 30pF-100 -30pF which are used for the microphone and data ports. There are also three C-L-C filters with values of 80pF-3nH-80pF which are designed for the stereo speaker port.
