The PCM2900EG4 is a single-chip USB stereo Audio Codec with USB-compliant full-speed protocol controller. The USB protocol controller works with no software code, but the USB descriptors can be modified in some areas (e.g., vendor ID/product ID). The PCM2900 employs SpAct? architecture, TI's unique system that recovers the audio clock from USB packet data. On-chip analog PLLs with SpAct architecture enable playback and record with low clock jitter and with independent playback and record sampling rates.
