Product Summary
The PCM2900BDBR is a Texas Instruments single-chip USB stereo audio codec with USB-compliant full-speed protocol controller and S/PDIF (only PCM2902). The PCM2900BDBR USB protocol controller works with no software code, but the USB descriptors can be modified in some areas (e.g., vendor ID/product ID). On-chip analog PLLs with SpAct enable playback and record with low clock jitter and with independent playback and record sampling rates. The applications of the PCM2900BDBR include USB Audio Speaker, USB Headset, USB Monitor, USB Audio Interface Box.
