Description

The CS4329 is a complete stereo digital-to-analog out-

put system. In addition to the traditional D/A function, the

CS4329 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 CS4329 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.
