l External Reference Input
l Pin-compatible with the CS4396
The CS43122 is a complete high performance 24 bit-
192 kHz stereo digital-to-analog conversion system. The
device includes a digital interpolation filter followed by an
oversampled 5 bit delta-sigma modulator which drives
second generation dynamic-element-matching (DEM)
selection logic. The output from the DEM block controls
the input to a multi-element switched capacitor DAC/low-
pass filter, with fully-differential outputs. This multi-bit ar-
chitecture features significantly lower out-of-band noise
and jitter sensitivity than traditional 1-bit designs, and the
advanced second generation DEM guarantees low noise
and distortion at all signal levels.
The CS43122 is the optimal D/A converter solution for
any application that requires the highest performance
and best possible sound quality including high-end con-
sumer and professional audio products such as
Universal DVD players, A/V receivers, Outboard D/A
Converters, CD Players, and Mixing Consoles.
