TIPCM2906CDB
Overview
The PCM2906CDB is a single-chip USB stereo audio codec designed for consumer and professional audio applications. It integrates 16-bit delta-sigma ADCs and DACs with a full-speed USB 2.0 compliant transceiver and an S/PDIF interface. The device is bus-powered, eliminating the need for an external power supply in many designs while supporting stereo record and playback functionality.
Why Choose This Part
This IC simplifies design by integrating the USB controller, clock generator, and audio converters into a single 28-SSOP package. It supports adaptive mode for playback and asynchronous mode for recording to optimize synchronization over USB. The inclusion of S/PDIF input and output provides additional flexibility for high-fidelity digital audio routing.
Applications
Key Specifications
Getting Started
Engineers can evaluate the device using the PCM2906CEVM-U evaluation module, which provides direct access to the analog and digital IOs. Since it is a USB-IF certified device, it typically utilizes standard OS USB audio drivers, removing the need for custom driver development. Ensure a stable 5V VBUS supply and a 12-MHz crystal for the on-chip clock generator.
