3 Description

The DIX4192-Q1 device 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 216 kHz. The DIR

lock range includes sampling rates from 20 kHz to

216 kHz.
