DIX4192TPFBRQ1

The Texas Instruments DIX4192-Q1 is an integrated digital audio interface receiver and transmitter designed for automotive and professional audio applications. This device supports both digital audio interface transmitter (DIT) and receiver (DIR) functions, enabling PCM/Encoded data to S/PDIF conversion and S/PDIF to Stereo PCM conversion, respectively. It supports sampling rates up to 216 kHz.

The DIX4192TPFBRQ1 features a user-selectable serial host interface, supporting both SPI and I2C protocols for access to on-chip registers and data buffers. It includes two audio serial ports (Ports A and B) that can operate in slave or master mode with sampling rates up to 216 kHz, supporting various data formats like Left-Justified, Right-Justified, and Philips I²S™. The device also offers four general-purpose digital outputs that are programmable through control registers.

This audio transceiver operates from 1.8-V core and 3.3-V I/O power supplies. It is qualified for automotive applications under the AEC-Q100 standard, with device temperature grades including Grade 3 (–40°C to +85°C) and Grade 2 (–40°C to +105°C). The component is housed in a compact 48-TQFP (7x7) package, suitable for surface mount applications.

Key features include extensive power-down support, allowing functional blocks to be disabled individually when not in use. The device also provides status registers and interrupt generation for flag and error conditions. Its design is compatible with SRC4382 and SRC4392.
