The PCM2912APJT is an audio CODEC with USB Interface mono microphone input and stereo headphone output. The USB protocol controller works with no software code, but USB descriptors can be modified on request. The PCM2912A employs SpAct? architecture, its unique system that recovers the audio clock from USB packet data. On-chip analogue PLLs with SpAct enables independent playback and record sampling rates with low clock jitters.
