The OPA was just a random op-amp i put in the sch to remind me there was one on the small PCB next to the printhead..

The LVDS receiver we used in the end was a DS90LV048A but we still get 100Mhz noise 50% of the time when there is no signal. any pulse you see that is less than 20ns you can ignore. I put the datasheet of the LVDS receiver in the eagle folder and added a Scan of the printout of the nozzletest that i used to trance the signals.
