ADV601LC屬于集成電路（IC）的編解碼器。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的ADV601LC編解碼器編解碼器是用于通過壓縮和解壓縮來轉(zhuǎn)換數(shù)據(jù)的半導體器件。數(shù)據(jù)壓縮可提高傳輸速度并減少存儲空間。某些編解碼器提供高達 32 位的分辨率，并且分別提供多達 6 個或 8 個模數(shù)轉(zhuǎn)換器和數(shù)模轉(zhuǎn)換器。除三角積分調(diào)制外，還有 I2C、I2S、SPI、串行、HDA、S/DIF、PCM、USB、AC'97 和 SLIMbus 數(shù)據(jù)接口。

GENERAL DESCRIPTION

The ADV601LC is an ultralow cost, single chip, dedicated function, all digital CMOS VLSI device capable of supporting visually loss-less to 350:1 real-time compression and decompression of CCIR-601 digital video at very high image quality levels. The chip integrates glueless video and host interfaces with on-chip SRAM to permit low part count, system level implementations suitable for a broad range of applications. The ADV601LC is 100 bitstream compatible with the ADV601.

The ADV601LC is a video encoder/decoder optimized for realtime compression and decompression of interlaced digital video. All features of the ADV601LC are designed to yield high performance at a breakthrough systems-level cost. Additionally, the unique sub-band coding architecture of the ADV601LC offers you many application-specific advantages. A review of the General Theory of Operation and Applying the ADV601LC sections will help you get the most use out of the ADV601LC in any given application.
