Hi im sharing a schematic that was designed in Altium can anyone share how can we implement this differential pair in our design in Altium.

What do you need to know?
- That you need to name your differential pair differently? --> \*_P and \*_N
- How to place differential pair directive? --> Place / Directives / Differential Pairs
- How to place the parameter set? --> Place / Directives / Parameter Set
- Or something else?

Hi
Thankyou for sharing documenting i will be reading out.
Yes, I want to know about placing parameters set and also pairing the directive also what is the use of differential pair i mean significance.

You use the parameters set to assign the characteristic impedance for the differential pair. This is only really useful if you need different impedances for different pairs.
