Z86228集成電路（IC）的編碼器解碼器轉換器規(guī)格書PDF中文資料

Z86228屬于集成電路（IC）的編碼器解碼器轉換器。由Zilog, Inc.制造生產的Z86228編碼器，解碼器，轉換器該系列產品可用于將信息封裝或編碼為適合于傳輸或存儲的格式，和/或在通信路徑的另一端執(zhí)行逆運算，通常是通過使用某些形式的調制過程。示例包括從數字數據生成模擬視頻信號的器件（反之亦然）；基于傳輸目的對按鈕的狀態(tài)進行編碼的器件（實現遠程控制功能）；以及便于將標準 UART 連接到標準紅外收發(fā)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.
