Z86228集成电路（IC）的编码器解码器转换器规格书PDF中文资料

Z86228属于集成电路（IC）的编码器解码器转换器。由Zilog, Inc.制造生产的Z86228编码器，解码器，转换器该系列产品可用于将信息封装或编码为适合于传输或存储的格式，和/或在通信路径的另一端执行逆运算，通常是通过使用某些形式的调制过程。示例包括从数字数据生成模拟视频信号的器件（反之亦然）；基于传输目的对按钮的状态进行编码的器件（实现远程控制功能）；以及便于将标准 UART 连接到标准红外收发器的器件。

GENERAL DESCRIPTION

The Z86228 (Line 21 Closed-Caption Controller) is a single I.C. designed to provide the functional performance of a L21C Decoder module. This Superintegration™ VLSI device is completely self contained requiring only composite video, a horizontal timing signal as input and an external keyer (i.e., video switch between TV video and ClosedCaption video) to produce captioned video. The Z86228 uses a wired logic approach to perform the functions selected through its input control signals. It is fabricated using standard CMOS technology and designed to achieve the lowest possible cost.
