    CS42516

    110 dB, 192 kHz 6-Ch Codec with S/PDIF Receiver

    Features

    Six 24-bit D/A, two 24-bit A/D Converters110 dB DAC / 114 dB ADC Dynamic Range-100 dB THD+NSystem Sampling Rates up to 192 kHzS/PDIF Receiver compatible with EIAJ CP1201 and IEC-60958

    Recovered S/PDIF CLK or System Clock Selection

    8:2 S/PDIF Input MUXADC High Pass Filter for DC Offset Calibration

    Expandable ADC Channels and One-line-Mode Support

    Digital Output Volume control with soft rampDigital +/-15dB Input Gain Adjust for ADCDifferential Analog ArchitectureSupports logic levels between 5 V and 1.8 V

    General DescriptionThe CS42516 codec provides two analog-to-digital and six dig-ital-to-analog delta-sigma converters, as well as an integratedS/PDIF receiver, in a 64-pin LQFP package.

    The CS42516 integrated S/PDIF receiver supports up to eightinputs, clock recovery circuitry and format auto-detection. Theinternal stereo ADC is capable of independent channel gaincontrol for single-ended or differential analog inputs. All sixchannels 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 CS42516 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.
