Texas Instruments  DIX4192IPFBR

The DIX4192 device is a highly-integrated CMOS device designed for use in professional and broadcast digital audio systems. The DIX4192 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 216 kHz. The DIR lock range includes sampling rates from 20 kHz to 216 kHz.

The DIX4192 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. An open-drain interrupt output pin is provided, and is supported by flexible interrupt reporting and mask options through control register settings. A master reset input pin is provided for initialization by a host processor or supervisory functions.

The DIX4192 device requires a 1.8-V core logic supply, in addition to a 3.3-V supply for powering portions of the DIR, DIT, and line driver and receiver functions. A separate logic I/O supply supports operation from 1.65 V to 3.6 V, providing compatibility with low voltage logic interfaces typically found on digital signal processors and programmable logic devices. The DIX4192 device is available in a lead-free, TQFP-48 package, and is pin- and register-compatible with the Texas Instruments SRC4382 and SRC4392 products.
