General Description
The CS42516 codec provides two analog-to-digital and six dig-
ital-to-analog delta-sigma converters, as well as an integrated
S/PDIF receiver, in a 64-pin LQFP package.
The CS42516 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 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 dynam-
ic range, negligible distortion and low noise, such as A/V
receivers, DVD receivers, digital speaker and automotive audio
systems.
