In addition to the traditional D/A function, the CS4327 includes a digital interpolation filter followed by an 128X oversampled delta-sigma modulator. The mod- ulator output controls the reference voltage input to an ultra-linear analog low-pass filter. This architecture al- lows for infinite adjustment of sample rate between 1 and 50 kHz while maintaining linear phase response simply by changing the master clock frequency. The CS4327 also includes an extremely flexible serial port utilizing mode select pins to support multiple inter- face formats. The master clock can be either 256, 384, or 512 times the input sample rate, supporting various audio environments.
