Product Summary

The PCM2902BDBR is a stereo audio codec with usb interface, single-ended analog input/output, and s/pdif. The USB protocol controller requires no software code, but the USB descriptors can be modified in some areas (for example, vendor ID and/or product ID). The PCM2902BDBR employs SpAct architecture, TI’s unique system that recovers the audio clock from USB packet data. The applications of the PCM2902BDBR include: USB Audio Speaker, USB Headset, USB Monitor, USB Audio Interface Box.
