CS42432  
108 dB, 192 kHz 4-in, 6-out TDM CODEC  
FEATURES  
GENERAL DESCRIPTION  
The CS42432 CODEC provides four multi-bit analog-to-dig-  
ital and six multi-bit digital-to-analog Delta-sigma  
converters. The CODEC is capable of operation with either  
differential or single-ended inputs and outputs, in a 52-pin  
MQFP package.  
z Four 24-bit A/D, Six 24-bit D/A Converters  
z ADC Dynamic Range  
– 105 dB Differential  
– 102 dB Single-ended  
z DAC Dynamic Range  
Four fully differential, or single-ended, inputs are available  
on stereo ADC1and ADC2. Digital volume control is provid-  
ed for each ADC channel, with selectable overflow  
detection.  
– 108 dB Differential  
– 105 dB Single-ended  
z ADC/DAC THD+N  
All six DAC channels provide digital volume control and can  
operate with differential or single-ended outputs.  
– -98 dB Differential  
– -95 dB Single-ended  
z Compatible with Industry-standard Time  
An auxiliary serial input is available for an additional two  
channels of PCM data.  
Division Multiplexed (TDM) Serial Interface  
DAC Sampling Rates up to 192 kHz  
z ADC Sampling Rates up to 96 kHz  
z Programmable ADC High-pass Filter for DC  
Offset Calibration  
The CS42432 is ideal for audio systems requiring wide dy-  
namic range, negligible distortion and low noise, such as  
A/V receivers, DVD receivers, and automotive audio  
systems.
