Copyright © Cirrus Logic, Inc. 2005 (All Rights Reserved) Cirrus Logic, Inc. http://www.cirrus.com CS42528 114 dB, 192 kHz 8-Ch Codec with S/PDIF Receiver Features Eight 24-bit D/A, two 24-bit A/D Converters 114 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 +/-15dB Input Gain Adjust for ADC Differential Analog Architecture Supports logic levels between 5 V and 1.8 V. 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.
