Quad Differential Transmitter

[jeremy0203]

Be easy on me, I am a newb.

Trying to build and have a pcb produced of a quad differential transmitter that i can use to send 4 signals over ethernet cable to an already existing quad receiver board. Will be using the AM26C31 driver (http://www.ti.com/lit/ds/symlink/am26c31.pdf) and the receiver uses the AM26C32. I will post a picture of a crude schematic I came up with real quick in Kicad. Is there really nothing to this than the IC and a 0.1uF cap as called out in the datasheet? I have seen a board that is meant to do the same thing and it has resistors on each of the 8 outputs, required? And if so what would be the purpose of those in the circuit? Any help would be appreciated. Thanks.

It's standalone, yes.

Mind that you still need a ground between transmitter and receiver.  If you're using CAT5 type cable, use shielded cable and tie the shield to circuit ground.

Otherwise, get the ground reference off the termination resistor (make a center tap), and use isolated receivers.

Termination resistors, thanks just read up on that and makes sense for this system.
