Product Summary
The PCM2901E/2K is a single-chip USB stereo audio codec. The USB protocol controller works with no software code, but the USB descriptors can be modified in some areas (for example, vendor ID/product ID). The PCM2901E/2K 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 and with independent playback and record sampling rates. The applications of the PCM2901E/2K include: USB Audio Speaker, USB Headset, USB Monitor, USB Audio Interface Box.
