PCM4222PFBR

The PCM4222PFBR is a 2-channel high-performance Analog-to-digital Converter (ADC) designed for use in professional audio applications. Offering outstanding dynamic performance, the PCM4222 supports 24-bit linear PCM, 1-bit direct stream digital (DSD) and 6-bit modulator data outputs. The multi-bit modulator output adds versatility, allowing customers to design their own digital decimation filter and processing hardware. The on-chip, linear phase decimation filtering engine supports classic and low group delay filter responses, allowing optimization for either studio or live sound applications. It includes three PCM sampling modes, supporting output sampling rates from 8 to 216kHz. The DSD output supports either 64x or 128x oversampled bit rates. The PCM4222 is configured using dedicated control pins for selection of output modes, PCM audio data formats and word length, decimation filter response, high-pass filter disable and reset/power-down functions.
