US Audio Multiplexing Decoder
Description
The CXA2094Q is an IC designed as a decoder for
the Zenith TV Multi-channel System and also
2
corresponds with I
C BUS. Functions include stereo
demodulation, SAP (Separate Audio Program)
demodulation, dbx noise reduction. Various kinds of
filters are built in while adjustment and mode control
2
are all executed through I
C BUS.
Features
• Adjustment free of VCO and filter.
• Audio
multiplexing
decoder
reduction decoder are all included in a single chip.
Almost any sort of signal processing is possible
through this IC.
• All adjustments are possible through I
allow for automatic adjustment.
• Various built-in filter circuits greatly reduce external
parts.
• There are two systems for external inputs.
• There is an additional SAP output.
