PCM2900B

The PCM2900B is Texas Instruments 'single-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, 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 as well as independent playback and record sampling rates.

Features of the PCM2900B are:(1)PCM2900B: Without S/PDIF; (2)On-Chip USB Interface: With Full-Speed Transceivers Fully Compliant with USB 2.0 Specification Certified by USB-IF Partially Programmable Descriptors (1) USB Adaptive Mode for Playback USB Asynchronous Mode for Record Bus Powered; (3)16-Bit Delta-Sigma ADC and DAC; (4)Sampling Rate: DAC: 32, 44.1, 48 kHz ADC: 8, 11.025, 16, 22.05, 32, 44.1, 48 kHz; (5)On-Chip Clock Generator with Single 12-MHz Clock Source.

The absolute maximum ratings of the PCM2900B can be summarized as:(1)Ambient temperature under bias : 40 to +125 ° C; (2)Storage temperature : 55 to +150 ° C; (3)Junction temperature :+150 ° C; (4)Lead temperature (soldering, 5s): +260 ° C; (5)Package temperature (IR reflow, peak): +250 ° C.
