Audio Codec 2ADC / 2DAC 16-Bit 28-Pin SSOP T/R, PCM2903BDBR, Texas Instruments

The PCM2903B is Texas Instruments" single-chip, USB, stereo audio codec with a USB-compliant full-speed protocol controller 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 PCM2903B employs SpAct architecture, TI"s unique system that recovers the audio clock from USB packet data. On-chip analog PLLs with SpAct enable playback and record with low clock jitter as well as independent playback and record sampling rates.
