LMH1297: incorrect connection by the end user

Part Number: LMH1297

If I have the SDI_IO+ line on LMH1297 configured as a cable driver and an SDI source is connected to SDI_IO+, will LMH1297 be harmed in any way?

    Hi Jordan,

    I thought i responded to this question yesterday.

    When connecting two cable driver output to one another this does not damage the part. Cable drivers normally have AC coupling capacitors and there is no DC path to damage the output put structure. Also, output structure is open collector and it limits the current sink.
