Описание

The PCM2903C is TIs 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. The PCM2903C employs SpAct™ architecture, TIs 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.

On-Chip USB Interface:
- With Full-Speed Transceivers
- Fully Compliant With USB 2.0 Specification
- Certified by USB-IF
- USB Adaptive Mode for Playback
- USB Asynchronous Mode for Record
- Self-Powered
16-Bit Delta-Sigma ADC and DAC
