LMH1982 output termination impedance

Other Parts Discussed in Thread: LMH1982

We have an application where the differential clock outputs of LMH1982 are running into Si5324 clock part. Can someone recommend a termination impedance?

The differential clock outputs from the LMH1982 are LVDS, and should be terminated in 100Ohms.

Thanks! Should the connection be AC coupled?

The eval board schematic shows 10nF ac coupling caps, so we'll go with that for now.
