US Audio Multiplexing Decoder
CXA2064M
Description
The CXA2064M is an IC designed as a decoder for
the Zenith TV Multi-channel System. Functions
include stereo demodulation, SAP (Separate Audio
Program) demodulation, dbx noise reduction.
30 pin SOP (Plastic)
Features
• Adjustment free of VCO and filter.
• Audio multiplexing decoder and dbx noise
reduction decoder are all included in a single chip.
Almost any sort of signal processing is possible
through this IC.
• Various built-in filter circuits greatly reduce external
parts.
• This IC is near pin to pin compatible with the
CXA2020M.
Applications
TV, VCR and other decoding systems for US audio
multiplexing TV broadcasting
