CS4228A集成电路（IC）的编解码器规格书PDF中文资料

CS4228A属于集成电路（IC）的编解码器。由凌云逻辑制造生产的CS4228A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 CS4228A codec provides two analog-to-digital and six digital-to-analog Delta-Sigma converters, along with volume controls, in a compact 28-pin SSOP device. Combined with an IEC958 (SPDIF) receiver (like the CS8414) and surround sound decoder (such as one of the CS492x or CS493xx families), it is ideal for use in DVD player, A/V receiver and car audio systems supporting multiple standards such as Dolby Digital AC-3, AAC, DTS, Dolby ProLogic, THX, and other multi-channel formats.
