CS42516 110 dB, 192 kHz 6-Ch Codec with S/PDIF Receiver Features Six 24-bit D/A, two 24-bit A/D Converters 110 dB DAC / 114 dB ADC Dynamic Range -100 dB THD+N System Sampling Rates up to 192 kHz S/PDIF Receiver Compatible with EIAJ CP1201 and IEC-60958 Recovered S/PDIF Clock or System Clock Selection 8:2 S/PDIF Input MUX ADC High-Pass Filter for DC Offset Calibration Expandable ADC Channels and One-Line Mode Support Digital Output Volume Control with Soft Ramp Digital +/-15 dB Input Gain Adjust for ADC Differential Analog Architecture Supports Logic Levels between 1.8 V and 5 V TXP RXP0 RXP1/GPO1 RXP2/GPO2 RXP3/GPO3 RXP4/GPO4 RXP5/GPO5 RXP6/GPO6 RXP7/GPO7 VARX AGND LPFLT General Description The CS42516 codec provides two analog-to-digital and six digital-to-analog delta-sigma converters, as well as an integrated S/PDIF receiver. The CS42516 integrated S/PDIF receiver supports up to eight inputs, clock recovery circuitry and format autodetection. The internal stereo ADC is capable of independent channel gain control for single-ended or differential analog inputs. All six 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 CS42516 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 CS42516 is available in a 64-pin LQFP package in both Commercial (-10° to 70° C) and Automotive (-40° to 85° C) grades. The CDB42518 Customer Demonstration board is also available for device evaluation. Refer to “Ordering Information” on page 89.

If Fs is lower than 46.875 kHz, the maximum CCLK frequency should be less than 128 Fs. This is dictated by the timing requirements necessary to access the Channel Status and User Bit buffer memory. Access to the control register file can be carried out at the full 6 MHz rate. The minimum allowable input sample rate is 8 kHz, so choosing CCLK to be less than or equal to 1.024 MHz should be safe for all possible conditions. 21. Data must be held for sufficient time to bridge the transition time of CCLK. 22. For fsck
