CS43122  
122 dB, 24-Bit, 192 kHz DAC for Digital Audio  
Features  
Description  
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.  
l 24 Bit Conversion  
l Up to 192 kHz Sample Rates  
l 122 dB Dynamic Range  
l -102 dB THD+N  
l Second-Order Dynamic-Element Matching  
l Low Clock Jitter Sensitivity  
l 102 dB Stop-band attenuation  
l Single +5 V supply  
l Soft Mute Control  
l Digital De-Emphasis for 32, 44.1, and 48 kHz  
l External Reference Input  
l Pin-compatible with the CS4396  
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.
