LMH0302: Use LMH0302 as a video driver with 75 ohm input and output?

Can I use LMH0302 to drive a cable when the input is a singled ended 75 ohm input?  Leave SDI# floating or terminate it with a 75 ohm to ground?  Thanks!

    Hi Tran,

    I see two issues with your approach:

    1). LMH0302 input is differential 100-ohm or single ended 50-ohm input. 

    2). LMH0302 is like a buffer or 75-ohm driver. It does not clean up any non-ideality due to signal integrity issues on its input. Therefor you would not get a clean signal on it's input. I don't know your application but you can use LMH0397 to receive from 75-ohm signal and transmit out on 75-ohm output as well.
