Z87010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

Z87010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Z87010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(hào)的器件（反之亦然）；基于傳輸目的對(duì)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。

GENERAL DESCRIPTION

The Z87010/Z87L10 is a second generation CMOS Digital Signal Processor (DSP) that has been ROM-coded by Zilog to provide full-duplex 32 Kbps, Adaptive Delta Pulse Code Modulation (ADPCM) speech coding/decoding (CODEC), and interface to the Z87000/Z87L00 Spread Spectrum Cordless Telephone Controller. Together the Z87000/Z87L00 and Z87010/Z87L10 devices support the implementation of a 900 MHz frequency-hopping spread spectrum cordless telephone in conformance with United States FCC regulations for unlicensed operation.
