Camera Link协议和FPGA的数字图像信号源设计

Design of numeral picture signal source based on Camera Link standard and FPGA

介绍一种基于Camera Link协议和FPGA设计数字图像信号源的方法。该设计将图像数据和接口信号转换成与Camera Link协议相匹配的低压差分信号(LVDS)进行传输。提高了信号的传输距离和精度,为图像数据采集装置的测试提供了可靠的信号源。阐述了图像信号源的设计思想与电路结构,最后简述了在实际中的应用。该信号源已经成功应用于某弹载地面测试系统中。

This paper introduces a kind of method to design the numeral picture signal source.that is based on Camera Link protocol and FPGA.The picture data and interface signal are converted to low voltage differential signaling（LVDS） matching the Camera Link standard to transmit.This method can enhance the signal transfers distance,precision and offer the trustiness signal source to picture data acquisition system.It elaborates the design and circuit structure of picture signal source.In the end,it elaborates its actual application.This signal source has already been applied to a ground testing system.
