DIX4192

SBFS031C – JANUARY 2006 – REVISED JUNE 2006

The DIX4192 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 216kHz. The DIR lock range includes

sampling rates from 20kHz to 216kHz.

The DIX4192 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 via control register

settings. A master reset input pin is provided for initialization by a host processor or supervisory functions.

The DIX4192 requires a +1.8V core logic supply, in addition to a +3.3V supply for powering portions of the DIR,

DIT, and line driver and receiver functions. A separate logic I/O supply supports operation from +1.65V to +3.6V,

providing compatibility with low voltage logic interfaces typically found on digital signal processors and

programmable logic devices. The DIX4192 is available in a lead-free, TQFP-48 package, and is pin- and

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be

more susceptible to damage because very small parametric changes could cause the device not to meet its published

specifications.

These limits are stress ratings only. Stresses beyond these limits may result in permanent damage. Extended exposure to absolute

maximum ratings may degrade device reliability. Normal operation or performance at or beyond these limits is not specified or ensured.
