General Description

The CS42418 codec provides two analog-to-digital and eight digital-to-analog delta-sigma converters, as well as an integrated PLL.

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.
