Hello,
In my future design I could win a lot of pins if I could drive a bus at
160MHz. Because of bank restrictions and because this bus is connected to a CPLD, I will have to use LVTTL. Has anybody tried driving a bus in LVTTL at 160MHz?I would prefer to use LVDS but the CPLD doesn't allow that. Lattice has LVDS CPLDs but only the large CPLDs support LVDS inputs.
I am afraid that this bus will have a lot of EMI/EMC problems. What do you think of it, should series termination be adequate to limit the EMI/EMC problems?
best regards, Dolphin
