We are evaluating a use case where an LVDS clock source drives a GTS transceiver reference clock input, which is typically configured for CML or HCSL standards.
Is this usage supported, particularly when using AC coupling between devices, as seen on the Agilex 5 Premium Development Kit?
What are the required pin configurations and electrical considerations (e.g., termination, biasing) to ensure proper operation?
Does this approach present any known limitations or risks?
