CS42448

108 dB, 192 kHz 6-in, 8-out CODEC

FEATURES

GENERAL DESCRIPTION

The CS42448 CODEC provides six multi-bit analog-to-digi-

tal and eight 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 64-pin

LQFP package.

z Six 24-bit A/D, Eight 24-bit D/A Converters

z ADC Dynamic Range

– 105 dB Differential

– 102 dB Single-ended

z DAC Dynamic Range

Six fully differential, or single-ended, inputs are available on

stereo ADC1, ADC2, and ADC3. When operating in Single-

ended Mode, an internal MUX before ADC3 allows selec-

tion from up to four single-ended inputs. Digital volume

control is provided for each ADC channel, with selectable

overflow detection.

– 108 dB Differential

– 105 dB Single-ended

z ADC/DAC THD+N

– -98 dB Differential

All eight DAC channels provide digital volume control and

can operate with differential or single-ended outputs.

– -95 dB Single-ended

z Compatible with Industry-standard Time

Division Multiplexed (TDM) Serial Interface

z System Sampling Rates up to 192 kHz

z Programmable ADC High-pass Filter for DC

Offset Calibration

An auxiliary serial input is available for an additional two

channels of PCM data.

The CS42448 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.

z Logarithmic Digital Volume Control

z I²C & SPI™ Host Control Port

z Supports Logic Levels Between 5 V and

1.8 V
