Original question:

LMX2594: RFoutB bias

LMX2594: clock input

Hi, would you have a replacement diagram for the reference clock input? What impedance can I expect at 50MHz single-ended and differential?

Thanks

    Hi,
    I'm not sure I know exactly what you mean by "Replacement Diagram", but I think that you are looking for the input impedance.

    At 50 MHz, it is very fair to assume this is high impedance, so you can put shunt 50 ohm (with AC couping) to make it look like 50 ohm.

    We do have IBIS model for this device as well.
