Abstract:

With ever increasing frequency of the signal,traditional parallel synchronous digital signal will reach its limit in digits and the rate,thus turning to find a way out from the high-speed serial signals,among which the low-voltage differential signaling (LVDS) is the most widely used.This paper presents the realization of LVDS signal from the aspects of PCB design,constraints,and signal integrity simulation setting with the design of high-speed FPGA-based signal downloader as an example.

Key words: LVDS;PCB design;signal integrity
