DIR9001IPWQ1

The Texas Instruments DIR9001IPWQ1 is a highly integrated digital audio interface receiver designed for automotive and consumer audio applications. It includes a low-jitter clock-recovery system capable of decoding biphase input signals, commonly known as S/PDIF, EIAJ CP-1201, IEC60958, and AES/EBU.

This device supports a wide sampling frequency range from 28 kHz to 108 kHz, with a maximum sampling rate of 96 kHz specified in its title and 108 kHz in product details. It offers a low-jitter recovered system clock with 50 ps jitter tolerance and selectable clock outputs including 128 fS, 256 fS, 384 fS, and 512 fS. The output formats include 24-bit I²S, 24-bit Left-Justified, and 16/24-bit Right-Justified serial audio data.

Operating on a single 3.3V power supply (2.7V to 3.6V range), the DIR9001IPWQ1 features 5V-tolerant digital inputs and a wide operating temperature range of -40°C to 85°C. It is housed in a 28-pin TSSOP package with a 0.65 mm pin pitch. The device is compliant with various digital audio interface standards, including IEC60958, JEITA CPR-1205, AES3, and EBU tech3250.

Applications for the DIR9001IPWQ1 include car audio head units, car audio external amplifiers, and other consumer audio systems requiring high-fidelity digital audio signal reception and processing.
