The newly developed Sp Act™ (Sampling Period Adaptive Controlled Tracking) system recovers a stable, lowjitter 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 48k Hz, 44.1k Hz and 32k Hz sampling rates, using either 16-bit stereo or monaural audio data. Digital attenuation and softmute features are included, and are controlled via USB audio class request. Patents Pending. Sp Act™ is a trademark of Burr-Brown Corporation.
