General Description
The CS42418 CODEC provides two analog-to-digital and eight digital-to-analog Delta-Sigma converters, as well as an integrated PLL, in a 64-pin LQFP package.
The CS42418 integrated PLL provides a low-jitter system clock. 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.
