The design of PCI express-based multi-channel LVDS signal transfer card

This paper described a high-speed LVDS data transfer card design and implementation which is based on PCI Express Bus. The transfer card can receive multiple high-speed LVDS data outside and integrate the multi-channel data in the FPGA to be conversed to PCI data form and transmitted to the PCI-PCI Express bridge chip, which will eventually pass the data PCI Express bus as the carrier to the computer for data analysis. This article focuses on the key technology of the system hardware design and PCI bus control logic. The adapter data transfer and reliable performance, and the card has been successfully used in engineering practice.
