General Description

The CS42528 codec provides two analog-to-digital and

eight digital-to-analog delta-sigma converters, as well

as an integrated S/PDIF receiver.

The CS42528 integrated S/PDIF receiver supports up

to eight inputs, clock recovery circuitry and format auto-

detection. The internal stereo ADC is capable of inde-

pendent channel gain control for single-ended or

differential analog inputs. All eight channels of DAC pro-

vide digital volume control and differential analog

outputs. The general-purpose outputs may be driven

high or low, or mapped to a variety of DAC mute con-

trols or ADC overflow indicators.

The CS42528 is ideal for audio systems requiring wide

dynamic range, negligible distortion and low noise, such

as A/V receivers, DVD receivers, digital speaker and

automotive audio systems.

The CS42528 is available in a 64-pin LQFP package in

both Commercial (-10° to 70° C) and Automotive

(-40° to 85° C) grades. The CDB42528 Customer Dem-

onstration board is also available for device evaluation.
