We did a test today and using a series resistor of 67ohms on each output of the LCX244 driver but no load capacitor and the signal was so much better than the LCX760. There was a small amount of ringing on each transition which was only obvious when using the oscilloscope in 100meg bandwidth mode and X10 probe. When limiting the bandwidth to 20Meg or using a X1 probe there was no ringing at all. There were no other spikes or other undesirable pulses which we were previously getting. I did not try any pull down capacitor but would expect it to filter out any remaining ringing on the signal.
Thank you for all the help. The pcb design will be updated on Monday and prototypes will be available in two weeks.
Great Forum
