CS42432
108 dB, 192 kHz 4-in, 6-out TDM CODEC
FEATURES
GENERAL DESCRIPTION
z Four 24-bit A/D, Six 24-bit D/A Converters
z ADC Dynamic Range
– 105 dB Differential
– 102 dB Single-ended
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 DAC Dynamic Range
Four fully differential, or single-ended, inputs are available
– 108 dB Differential
– 105 dB Single-ended
z ADC/DAC THD+N
– -98 dB Differential
– -95 dB Single-ended
z Compatible with Industry-standard Time
on stereo ADC1and ADC2. Digital volume control is provid-
ed for each ADC channel, with selectable overflow
detection.
All six DAC channels provide digital volume control and can
operate with differential or single-ended outputs.
An auxiliary serial input is available for an additional two
channels of PCM data.
Division Multiplexed (TDM) Serial Interface _{The CS42432 is ideal for audio systems requiring wide dy-}
