Texas Instruments DIX4192IPFBG4

Description
The DIX4192 is a highly integrated digital audio interface (DAI) device that combines a digital audio interface transmitter (DIT), a digital audio interface receiver (DIR), and two audio serial ports (ASP) in a single package. The DIT includes a differential line driver and CMOS buffered outputs, while the DIR includes four differential input line receivers and an input multiplexer. Both the DIT and DIR have blocksized data buffers for both channel status and user data, as well as status registers and interrupt generation for flag and error conditions. The ASPs provide a synchronous serial interface to external signal processors, data converters, and logic. The DIX4192 operates from a 1.8V core and 3.3V I/O power supply and is available in a small TQFP48 package.
