DESCRIPTION
– Decimation Digital Filter:
The PCM2906C is Texas Instruments' single-chip,
– Passband Ripple = ±0.05 dB
USB, stereo audio codec with a USB-compliant
full-speed protocol controller and S/PDIF. The USB
– Stop-Band Attenuation = –65 dB
protocol controller requires no software code. The
– Single-Ended Voltage Input
PCM2906C employs SpAct™ architecture, TI's
– Antialiasing Filter Included
unique system that recovers the audio clock from
– Digital HPF Included
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.
