hi all.
I’m designing a pcb board with spartan-6 and w5300 TCP/IP module.
in datasheet of w5300 say’s for better impedance matching you have to place 50ohm res and 0.1uf cap like the picture
. I’m using HR911105A rj-45 connector with magnetic module.
this connector uses 75ohm resistor and 1000pf cap the schematic is like this
my question is despite the 75 ohm resistor’s and 1000pf capacitors in this connector do i still need to place 50 ohm and 100nf cap?
