Hi, I am the Ph.D student of Stevens Institute of Technology. Our group currently try to build our own a Time-to-digital converter (FMC) that will interact with the Zedboard via FMC connector. This TDC will output LVDS signals, therefore, we plan to use bank 34,35 differential signals. I have a question about the circuit design.
The Hardware User Guide data sheet mentioned that the LPC FMC requirement is a 50-Ohms impedance single ended. I am not quite sure what that means. Does that mean we need to connect a 100-Ohms impedance between our differential signals? Or the 100-Ohms impedance is already the load out from the FMC and we just need to hook up our differential signals directly to the FMC? Thank you.
