DIX4192IPFBR-Q1 Interface Receiver & Transmitter Texas Instruments DIX4192IPFBR-Q1 Audio Interface Receiver & Transmitter is a highly-integrated CMOS device designed for use in professional and broadcast digital audio systems. The DIX4192-Q1 combines a digital audio interface receiver (DIR) and transmitter (DIT), two audio serial ports, and flexible distribution logic for interconnection of the function block data and clocks. The DIR and DIT are compatible with the AES3, S/PDIF, IEC 60958, and EIAJ CP-1201 interface standards. The audio serial ports and DIT may be operated at sampling rates up to 216kHz. The DIR lock range includes sampling rates from 20kHz to 216kHz. The DIX4192-Q1 device is configured using on-chip control registers and data buffers, which are accessed through either a 4-wire serial peripheral interface (SPI) port, or a 2-wire Philips I2C bus interface. Status registers provide access to a variety of flag and error bits, which are derived from the various function blocks.
