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
datasheet of HR91115A
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?
