DIX4192IPFB

The Texas Instruments DIX4192IPFB is an integrated digital audio interface receiver and transmitter, designed for high-fidelity audio applications. This transceiver IC supports sampling rates up to 216 kHz, making it suitable for demanding audio processing tasks.

Key electrical features include user-selectable serial host interfaces (SPI or I2C) and differential line drivers with CMOS-buffered outputs. The device integrates both a Digital Audio Interface Transmitter (DIT) and a Digital Audio Interface Receiver (DIR) with PLL lock range supporting sampling rates from 20 kHz to 216 kHz. It also includes automatic detection of non-PCM audio streams and audio CD Q-channel sub-code decoding.

Designed for surface mount, the DIX4192IPFB comes in a compact 48-TQFP package (7x7 mm). It operates from a 1.8-V core and 3.3-V I/O power supply, with an operating temperature range of -40°C to 85°C. The IC is well-suited for applications in automotive audio and professional audio systems.

This device offers extensive power-down support, allowing functional blocks to be disabled individually when not in use. It supports various audio data formats including Left-Justified, Right-Justified, and Philips I²S, with audio data word lengths up to 24 bits.
