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. Refer to “Ordering Information” on page 89.
