Avnet 公司的EXP视频模块提供了完整的前端视频功能,连接到具有EXP使能的基板,包括中等范围的视频处理,提供DVI,分量视频 S视频和VGA的视频输入,视频输出包括DVI,VGA和LCD屏,采用各种基于FPGA系列的处理,就能很容易实行真正的多媒体接口.本文介绍了EXP视频模块主要特性,架构图,TVP7001高清(HD)和TVP5150标清(SD)视频译码器接口框图,数字视频输入和数字/模拟视频输出接口框图,以及LCD视频输出接口框图,EXP视频模块电路图和材料清单.

The EXP Video Module from Avnet Electronics Marketing offers designers a full compliment of “pro-sumer” level front end video functions. The EXP formatted module connects to any EXP enabled baseboard for easy integration and prototyping with various FPGA families. Functions included on the module address the mid-range of video processing applications. The EXP Video module provides video inputs for DVI, component, composite, S-video, and VGA. Video outputs are available in DVI, VGA, and LCD panel. The LCD panel support includes a standard 10-bit LVDS interface as well as an 8-bit RGB parallel interface. Two image sensor inputs are provided for either 10-bit parallel input or serial differential input. A stereo audio CODEC device enables audio input and output features, making the EXP Video module a true multi-media interface for FPGA-based processing.
