Product details

DIR9001PWR – 96-kHz, 24-Bit Digital Audio Interface Receiver (S/PDIF)
DIR9001PWR from Texas Instruments is a high-performance S/PDIF digital audio receiver featuring low-jitter clock recovery and broad compatibility with professional and consumer digital audio standards.

Product Introduction

DIR9001PWR is a one-chip digital audio interface receiver designed to decode biphase-encoded digital audio signals such as S/PDIF (IEC60958), AES3, and EBU. It supports sampling frequencies from 28 kHz up to 108 kHz with 24-bit audio resolution.

The device integrates a low-jitter clock recovery system, delivering excellent audio fidelity without requiring an external clock source for standard decoding operation. Parallel hardware control pins allow easy configuration, making DIR9001PWR suitable for designs without a microcontroller.

Housed in a compact TSSOP-28 (PWR) package and operating from a single 3.3 V supply, DIR9001PWR is widely used in cost-sensitive and space-constrained digital audio systems.

Key Benefits

Low-Jitter Audio Performance

Advanced clock recovery minimizes jitter, ensuring clean and accurate digital-to-audio conversion.

Wide Standard Support

Compatible with S/PDIF, AES3, and EBU digital audio interface standards.

No External Clock Required

Internal sampling frequency calculation simplifies system design and reduces BOM cost.

Hardware-Only Control

Parallel control pins allow operation without firmware or MCU intervention.

Features

  • One-chip digital audio interface receiver (DIR)
  • Low-jitter recovered system clock (typ. 50 ps)
  • Sampling frequency range: 28 kHz to 108 kHz
