Description

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.
