I'm working with an MCP37231/21-200 that requires a differential input for the clock. I need to know if I can use an LVDS input to drive my clock. The output clock is specified to have LVDS capabilites, but the input clock does not state that.

From my understanding, LVDS inputs have a differential voltage of ~350mVpp, so it should work in this application. I'm also concerned about the common-mode voltage from the LVDS pair and the internally-generated common-mode voltage.

Would using an LVDS type signal be appropriate?

    \$\begingroup\$ Do you have a choice as to whether to use LVDS or something else? If you have a choice, LVPECL has better jitter characteristics than LVDS. If you AC couple and terminate before the AC coupling, then LVDS should work fine. \$\endgroup\$ – crj11 Apr 24 '18 at 14:42
