PCM2912A

The PCM2912A is the Texas Instruments single-chip,USB stereo audio codec with a USB 2.0-compliant full-speed protocol controller and an analog front-end (AFE) function for headset applications. The USB protocol controller works with no software code, but USB descriptors can be modified on request(1). The PCM2912A employs SpAct ™ architecture, TI ' s unique system that recovers the audio clock from USB packet data. On-chip analog PLLs with SpAct enables independent playback and record sampling rates with low clock jitters.

Features of the PCM2912A are:(1)On-Chip USB Interface: With Full-Speed Transceivers Fully Compliant with USB 2.0 Specification Certified By USB-IF Partially Programmable Descriptors Adaptive Isochronous Transfer for Playback Asynchronous Isochronous Transfer for; (2)Record Bus Powered; (3)16-Bit Delta-Sigma ADC and DAC ; (4)Sampling Rate: 8, 11.025, 16, 22.05, 32, 44.1, 48 kHz ; (5)On-Chip Clock Generator: With Single 6-MHz Clock Source.

The absolute maximum ratings of the PCM2912A can be summarized as:(1)Input current (any pins except supplies) :± 10 mA; (2)Ambient temperature under bias : 40 to +125 ° C; (3)Storage temperature: 55 to +150 ° C; (4)Junction temperature :+150 ° C.
