ADV611屬于集成電路（IC）的編解碼器。由亞德諾半導體技術有限公司制造生產(chǎn)的ADV611編解碼器編解碼器是用于通過壓縮和解壓縮來轉換數(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)轉換器和數(shù)模轉換器。除三角積分調制外，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 ADV611/ADV612 are low cost, single chip, dedicated function, all-digital-CMOS-VLSI devices capable of supporting visually loss-less to 7500:1 real-time compression and decompression of CCIR-601 digital video at very high image quality levels. The chips integrate 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 ADV611/ADV612 are 100 bitstream compatible with the ADV601. The ADV611/ADV612 comes in a 120-lead LQFP package.
