Camera Link - FPGA I/O protection

For a new desing I am planning to implement the Deserializer for CamerLink in the FPGA to replace the Deserializer chip. To protect the FPGA I/O's (ESD) I thought to place a "sacrificial" LVDS buffer...

In my opinion your concerns on ESD are rightful. If you go out your own 'box' with a cable to an external device you need some extra (ESD) protoction. HDMI, DVI video interfaces have similar needs, might be you find components there that fit you needs. An equalizer is also worth considering, it cost little more but it cleans your incoming signal, protects the fpga and makes the receiving problems (eg dealing with jitter) a lot easier.
