General Description

The CS42528 codec provides two analog-to-digital and eight

digital-to-analog delta-sigma converters, as well as an integrat-

ed S/PDIF receiver, in a 64-pin LQFP package.

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 independent channel gain

control for single-ended or differential analog inputs. All eight

channels of DAC provide 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 controls or

ADC overflow indicators.

The CS42528 is ideal for audio systems requiring wide dynam-

ic range, negligible distortion and low noise, such as A/V

receivers, DVD receivers, digital speaker and automotive audio

systems.
