Hello Ibrahim
Thanks for your reply
operating frequency max is 66 mhz
Hi Gurus
I am designing a board in which I want 50 ohms Zo for some 60% traces
and rest of the traces 65 ohms
but I am getting the trace width difference for both the impedance calculations
which is a bit problem in that I cannot complete the board
and I cant also restrict the signals to specific layers
So if I use 60ohms and 65 ohms traces will it make much of a difference in
operation
actually 65 ohms is for CPCI which I cant change and 50 ohms is for all TTL
level logic if I make this 50 as 60 ohms what difference will it make to the
operation
Thanks in advance
