PCM2900BDB Datasheet

Interface - CODECs


The PCM2900BDB /2902B is Texas Instrumentssingle-chip, USB, stereo audio codec with a USB-compliant full-speed protocol controller and S/PDIF (PCM2902B only). 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 PCM2900B/2902B employs SpAct™ architecture, TIs 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 as well as independent playback and record sampling rates. PCM2900BDB Features • PCM2900B: Without S/PDIF• PCM2902B: With S/PDIF• 16-Bit Delta-Sigma ADC and DAC• On-Chip Clock Generator with Single 12-MHz Clock Source• 28-Pin SSOP Package PCM2900BDB Applications • USB Audio Speaker• USB Headset BUS)• USB Monitor• USB Audio Interface Box
