US Audio Multiplexing Decoder
For the availability of this product, please contact the sales office.
Description
The CXA1784AS is an IC designed as a decoder
for the Zenith TV Multi-channel System and also
corresponds with I
2
C BUS. Functions include stereo
demodulation, SAP (Separate Audio Program)
demodulation, dbx noise reduction and sound
processor. Various kinds of filters are built in while
adjustment, mode control and sound processor
control are all executed through I
2
C BUS.
Features
Audio multiplexing decoder, dbx noise reduction
decoder and sound processor are all included in a
single chip. Almost any sort of signal processing is
possible through this IC.
All adjustments are possible through I
2
C BUS to
allow for automatic adjustment.
Various built-in filter circuits greatly reduce external
parts.
There are two systems for both inputs and outputs,
and each mode control is possible.
