CXA1734S Datasheet | Sony Semiconductor Solutions

Description The CXA1734S is an IC designed as a decoder for the Zenith TV Multi-channel System also corresponds with I2C BUS. Functions include stereo demodulation, SAP (Separate Audio Program) demodulation and dbx noise reduction. Various kinds of filters are built in while adjustment and mode control are all executed through I2C BUS. Features - 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. - All adjustments are possible through I2C BUS to allow for automatic adjustment. - Various built-in filter circuits greatly reduce external parts.
