摘要
Abstract
This paper tries to exam the transmission bandwidth by establishing a scientific test-platform.The paper provides a test pattern formed by 10 bit raw image data which is generated by FPGA as transmitter.The receiver performs data conversion serial-to-parallel and then sends image data as well as clock and enable signals to the image grabber.The transmission reliability is estimated by checking the real-time received test pattern through the 3-wire LVDS serial port.From abundant experiments, the paper gets two results: when LVDS is implemented by imbedding modules in FPGA, transmission bandwidth is approx 152 Mbit/s; when LVDS is implemented by special LVDS devices, transmission bandwidth is approx 125.2 Mbit/s.In practical application cases, bandwidth derating is advised.关键词
