DIR9001IPWRQ1 Description

Short technical summary and product information.

The Texas Instruments DIR9001IPWRQ1 is a highly integrated digital audio interface receiver (DIR) IC. It features a low-jitter clock-recovery system and is compliant with major digital audio interface standards including IEC60958, JEITA CPR-1205, AES3, and EBU tech3250.

This device decodes biphase input signals, commonly known as S/PDIF, and offers a wide sampling frequency range from 28 kHz to 108 kHz. It provides a low-jitter recovered system clock with 50 ps jitter tolerance and supports selectable recovered system clock outputs. The DIR9001IPWRQ1 offers multiple serial audio data output formats, including 24-bit I²S, left-justified, and right-justified.

Designed for surface mount applications, the DIR9001IPWRQ1 comes in a 28-pin TSSOP package with a 0.65 mm pin pitch. It operates within a wide temperature range of -40°C to 85°C and requires a single 3.3V power supply (2.7V to 3.6V). The IC includes 5V-tolerant digital inputs and features parallel hardware function control. It is suitable for automotive head units, external amplifiers, and other consumer audio equipment.
