ADV611集成电路（IC）的编解码器规格书PDF中文资料

ADV611属于集成电路（IC）的编解码器。由亚德诺半导体技术有限公司制造生产的ADV611编解码器编解码器是用于通过压缩和解压缩来转换数据的半导体器件。数据压缩可提高传输速度并减少存储空间。某些编解码器提供高达 32 位的分辨率，并且分别提供多达 6 个或 8 个模数转换器和数模转换器。除三角积分调制外，还有 I2C、I2S、SPI、串行、HDA、S/DIF、PCM、USB、AC'97 和 SLIMbus 数据接口。

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.
