Theinternal stereo ADC is capable of independent channel gaincontrol for single-ended or differential analog inputs. All eightchannels of DAC provide digital volume control and differentialanalog outputs. The general purpose outputs may be drivenhigh or low, or mapped to a variety of DAC mute controls orADC overflow indicators.The CS42528 is ideal for audio systems requiring wide dynam-ic range, negligible distortion and low noise, such as A/Vreceivers, DVD receivers, digital speaker and automotive audiosystems.ORDERING INFORMATIONCS42528-CQZ -10° to 70° C 64-pin LQFP Lead FreeCS42528-DQZ -40° to 85° C 64-pin LQFP Lead FreeCDB42528 Evaluation BoardRSTRXP0RXP1/GPO1AD0/CSSCL/CCLKSDA/CDOUTAD1/CDINVLCAOUTA1+AOUTA1-AOUTB1+AOUTA3+AOUTA3-AOUTA2-AOUTB2-AOUTA2+AOUTB2+AOUTB1-AOUTB3+AOUTB3-AOUTA4+AOUTA4-AOUTB4+AOUTB4-AINL+AINL-AINR+AINR-FILT+REFGNDVQ RefADC#1ADC#2Digital FilterDigital FilterGain & ClipGain & Clip CX_SDOUTADCIN1ADCIN2CX_SCLKCX_LRCKCX_SDIN4CX_SDIN3CX_SDIN2CX_SDIN1VLSSAI_LRCKSAI_SCLKSAI_SDOUTDGND VDOM CKRM CKLPFLTTXPINTRx Clock/DataRecoveryS/PDIFDecoderDEMSerialAudioInterfacePortC&U BitData Buffer ControlPortDAC#1DAC#2DAC#3DAC#4DAC#5DAC#6DAC#7DAC#8Digital FilterVolume ControlDGNDRXP2/GPO2RXP3/GPO3RXP4/GPO4RXP5/GPO5RXP6/GPO6RXP7/GPO7VDM UTECGPOM UTEAnalog FilterVARX AGNDADCSerialDataAGNDVAInternal M CLKCODECSerialPortM ult/DivForm atDetectorAVR347 harman/kardon195
