High-speed image acquisition system based on camera link

A high-speed image acquisition system based on Camera Link is presented in this paper. This system uses LVDS(Low Voltage Differential Signaling) transmitter to convert 28-bit parallel data signals into four LVDS data streams according to Camera Link, and a phase-locked transmit clock is transmitted in parallel with the data streams over a fifth LVDS link. These serial streams are disposed. and stored with parallel data signals that are converted by LVDS receiver. Using Camera Link simplifies transferring a 28-bit bus over PCB traces and cables. This system not only saves cost by narrowing data paths that in turn reduce PCB layers. cable width, and connector size and pins but also can satisfy high image acquisition speed.
