CS4221集成电路（IC）的编解码器规格书PDF中文资料

CS4221属于集成电路（IC）的编解码器。由凌云逻辑制造生产的CS4221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。

描述 Description

The CS4220/1 is a highly integrated, high performance, 24-bit, audio codec providing stereo analog-to-digital and stereo digital-to-analog converters using delta-sigma conversion techniques. The device operates from a single +5 V power supply, and features low power consumption. Selectable de-emphasis filter for 32, 44.1, and 48 kHz sample rates is also included.
