DESCRIPTIONThe PCM2702 is a single chip digital-to-analog converter
offering two D/A output channels and an integrated USB 1.0
compliant interface controller. The newly developed SpAct™
(Sampling Period Adaptive Controlled Tracking) system re-
covers a stable, low-jitter clock for internal PLL and DAC
operation from the USB interface audio data.
The PCM2702 is based upon Texas Instruments Enhanced
Multi-level Delta-Sigma Modulator, an 8x oversampling digi-
tal interpolation filter, and an analog output low-pass filter.
The PCM2702 can accept a 48kHz, 44.1kHz and 32kHz
sampling rates, using either 16-bit stereo or monaural audio
data. Digital attenuation and soft-mute features are included,
and are controlled via USB audio class request.
Patents Pending.
