tia 644

Hi there - I hope someone could hel me out with a short information - I'm designing an LVDS-Driver/Receiver and have right now here only the IEEE-LVDS-1596 Standard. They say that the differential input resistance on the receiver sid should be within 90 to 110 ohm. How are the values for the TIA standard ?

I'm right now discussing about using Poly-resistors - but without additional effort we only get +/-20% max deviation - so no chance to fullfill the IEEE-standard - thought that this might be a little bit more relaxed in the TIA-standard ...
