CXA2174S

US Audio Multiplexing Decoder

Description

30 pin SDIP (Plastic)

The CXA2174S is an IC designed as a decoder for

the Zenith TV Multi-channel System and also

corresponds with I²C BUS. Functions include stereo

demodulation, SAP (Separate Audio Program)

demodulation, dbx noise reduction and sound

processor. Various kinds of filters are built-in this IC.

Adjustment, mode control and sound processor

control are all executed through I²C BUS.
