What is the AC coupling capacitor recommendation for E-tile reference clock input? - What is the AC coupling capacitor recommendation for E-tile reference clock input? Description It is recommended to add external AC coupling capacitors given the E-tile reference clock input buffer structure. Resolution There are two internal 50ohm terminations that will act as 100ohm parallel termination. See the Intel® Stratix® 10 TX Signal Integrity Development Kit for an example of these capacitors.
