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.
