Milt,

Do you know by any chance where may I find a differential impedance
calculator?
Thank you.

Pair.

traces.
> The LVDS Driver can be used with resistor values from 90 to 120 ohms and
provide the specified VOC.
> The manufacturers use split resistors so the VOS specification in TIA/EIA
644 can be monitored.
