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 I
2
C 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
register-compatible with the Texas Instruments SRC4382 and SRC4392 products.
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.
