Z8623012PSC屬于集成電路（IC）的編碼器解碼器轉(zhuǎn)換器。由Zilog, Inc.制造生產(chǎn)的Z8623012PSC編碼器，解碼器，轉(zhuǎn)換器該系列產(chǎn)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(diào)制過程。示例包括從數(shù)字數(shù)據(jù)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(xiàn)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。

ARCHITECTURAL OVERVIEW

The Z86230 is a stand-alone integrated circuit, capable of processing Extended Data Services (XDS) in Field 2 of the Vertical Blanking Interval (VBI) of a video frame. This device conforms to the transmission format defined in the Television Decoder Circuits Act of 1990, in accordance with the Electronics Industry Association specification EIA-608A and EIA-744A.

In addition, the Z86230 is ideally suited to monitor Picture-In-Picture (PiP) window video for violence blocking and other XDS data services. Highlights of the Z86230 include:

1. A stand-alone Line 21 Decoder for Extended Data Services (XDS).

2. Extractable XDS data from the input video.

3. Full output of a selectable V-Chip Program Blocking signal (PB).

4. Selectable XDS filter parameters from a list of preprogrammed values.

5. Minimal communications and control overhead that provides simple

implementation of Violence Blocking and Auto Clock Set Features.

6. Full output of the recovered XDS data through the I2C serial communication

port.

7. Two different slave addresses that are selectable in the I2C serial

communication port.

8. Selectable NTSC or PAL operation
