Présentation

Description

The DIR9001PW is a digital audio interface receiver from Texas Instruments, designed to extract and reclock S/PDIF or TOSLINK signals with high precision. It supports sample rates up to 96 kHz and features low jitter (<50 ps) for improved audio quality.
Key features:
- Wide input tolerance (3.3V–5V)
- Auto-detect sample rates (32–96 kHz)
- Low power consumption (~50 mW)
- I²S output for easy DAC interfacing
Commonly used in CD players, DACs, and home theater systems, the DIR9001PW ensures stable, jitter-free digital audio transmission. Its compact TSSOP-16 package makes it suitable for space-constrained designs.
For detailed specs, refer to the datasheet.

Pinout

The DIR9001PW is a 28-pin TSSOP package digital audio interface receiver. Key functions include:
- Supports S/PDIF, AES/EBU, IEC 60958 inputs (up to 216kHz sample rate).
- Jitter attenuation with low intrinsic jitter (<50ps).
- I²S output (24-bit, left-justified, or right-justified formats).
- System clock output (256×, 384×, or 512× Fs).
- Hardware control (no software required) for mode selection.
- 3.3V operation with 5V-tolerant inputs.
Pins include power (VDD, GND), input (SCKI, DATA), output (BCKOUT, LRCKOUT, DATAOUT), and configuration (M0, M1, M2).
