DESCRIPTION
The PCM2702 is a single chip digital-to-analog con-
verter offering two D/A output channels and an inte-
grated USB 1.0 compliant interface controller. The
newly developed SpAct™ (Sampling Period Adaptive
Controlled Tracking) system recovers a stable, low-
jitter clock for internal PLL and DAC operation from
the USB interface audio data.
The PCM2702 is based upon Burr-Brown’s Enhanced
Multi-level Delta-Sigma Modulator, an 8x
oversampling digital 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.
