STA016T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

STA016T屬于集成電路（IC）的編碼器解碼器轉(zhuǎn)換器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的STA016T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。

DESCRIPTION

The STA016 is a single chip MPEG 1, 2 and 2.5 Layer III audio decoder with embedded CDROM decoding capability. It can be easily connected to most existing CDDSP devices via a software configurable serial link. A tipical application block diagram is show in Figure 1. Besides MPEG decoding the device can also perform ADPCM encoding/decoding from different audio sources and the encoded stream, for instance, can be stored on an external flash memory.

A useful bypass mode allow using this device also as an audio processor for volume and tone controls.
