LMH0302SQE/NOPB - Differential output

Other Parts Discussed in Thread: DS30BA101

Hello,

I wanted to know whether the output pin SDO & SDO bar could be used as differential output pins.

If yes, possible way to implement it.

Thank you and regards,

Nishmitha

    Hi Nishmitha,

    In which way do you wish to make the outputs differential? Are you looking for (1) a differential 150-Ohm output, or (2) a differential 100-ohm implementation?

    If it is Option (1), I have not seen a need for this in previous customer use cases, so I would like to understand the application further if you have more details.

    If it is Option (2), I recommend taking a look at a similar device, the DS30BA101, which is based on a similar design but has been tested for use cases driving 100-Ohm differential cable or 75-Ohm single ended by adjusting the output voltage amplitude and the termination resistors at the output of the DS30BA101.

    Thanks,

    Michael

    Hi Michael,

    Thanks a lot.
    I will go with option 2.
