CS42418集成电路（IC）的编解码器规格书PDF中文资料

CS42418属于集成电路（IC）的编解码器。由凌云逻辑制造生产的CS42418编解码器编解码器是用于通过压缩和解压缩来转换数据的半导体器件。数据压缩可提高传输速度并减少存储空间。某些编解码器提供高达 32 位的分辨率，并且分别提供多达 6 个或 8 个模数转换器和数模转换器。除三角积分调制外，还有 I2C、I2S、SPI、串行、HDA、S/DIF、PCM、USB、AC'97 和 SLIMbus 数据接口。

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.
