Overview
CXA2074Q/S US Audio Multiplexing Decoder Description The CXA2074Q/S 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 while adjustment, mode control and sound processor control are all executed through I2C 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 I2C BUS to allow for automatic adjustment.
• Various built-in filter circuits greatly reduce external parts.
• There are three systems for inputs and two systems for outputs, and each mode control is possible.
