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.
