DESCRIPTION

Stereo ADC

− Analog Performance at V

− THD+N = 0.01%

The PCM2900/2902 is Texas Instruments single-chip

USB stereo audio codec with USB-compliant full-speed

protocol controller and S/PDIF (only PCM2902). The

USB protocol controller works with no software code,

but the USB descriptors can be modified in some areas

(e.g., vendor ID/product ID). The PCM2900/2902

employs SpAct architecture, TI’s unique system that

recovers the audio clock from USB packet data. On-chip

analog PLLs with SpAct enable playback and record with

low clock jitter and with independent playback and record

sampling rates.

= 5 V

BUS

− SNR = 89 dB

− Dynamic Range = 89 dB

− Decimation Digital Filter

− Pass-Band Ripple = 0.05 dB

− Stop-Band Attenuation = –65 dB

− Single-Ended Voltage Input

− Antialiasing Filter Included

− Digital LCF Included
