I am trying to interface an LVPECL differential signal (from a Micrel SY58012U) with the GTP of a XEM6310MT board.
It should be possible but I am seeing bit errors (probably about 2 bit errors every 50 bits). I am receiving the K characters I am transmitting from another system but with corruptions.
Coupling capacitors have been installed for all of the RX pairs but a value is not noted, I am presuming they are 100nF.
Has anyone else tried to connect LVPECL signals to the XEM6310MT board?
Do you have any suggestions for termination?
