termination resistor values for daisy chained LVDS app

Question asked by eltury on Dec 5, 2014

I am using ADN4665 & ADN4666 to extend an SPI bus. My cables are twisted pair. I have 100 ohm termination resistors on each board of which there can be a total of 4 daisy chained. Three run fine. When I add the 4th I have weird things happening to my signals. I suspect that my total termination R is too low at this point. Does someone have experience along these lines and perhaps can suggest what termination R might work?

Thanks for your help.
