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.
Advanced clock recovery minimizes jitter, ensuring clean and accurate digital-to-audio conversion.
Compatible with S/PDIF, AES3, and EBU digital audio interface standards.
Internal sampling frequency calculation simplifies system design and reduces BOM cost.
Parallel control pins allow operation without firmware or MCU intervention.
