I need to route the 4 pairs of TP ethernet wires from a 10/100BASE-T NIC card through 2 feet of board traces (approx 50 ohms of impedance) back out to Cat5E (100 ohm impedance) cable. Or do I need anything at all?
Can I use matching magnetics on either side of the 50ohm traces to eliminate this disconuity?
such as 1:.7 & 1:1.4?
Thanks in advance
