AD725集成電路（IC）的編碼器解碼器轉(zhuǎn)換器規(guī)格書PDF中文資料

AD725屬于集成電路（IC）的編碼器解碼器轉(zhuǎn)換器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD725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(chǔ)的格式，和/或在通信路徑的另一端執(zhí)行逆運(yùn)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?jǐn)?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(jìn)行編碼的器件（實(shí)現(xiàn)遠(yuǎn)程控制功能）；以及便于將標(biāo)準(zhǔn) UART 連接到標(biāo)準(zhǔn)紅外收發(fā)器的器件。

PRODUCT DESCRIPTION

The AD725 is a very low cost general purpose RGB to NTSC/PAL encoder that converts red, green and blue color component signals into their corresponding luminance (baseband amplitude) and chrominance (subcarrier amplitude and phase) signals in accordance with either NTSC or PAL standards. These two outputs are also combined on-chip to provide a composite video output. All three outputs are available separately at voltages of twice the standard signal levels as required for driving 75 ?, reverse-terminated cables.
