HD3SS3202: Need better crosstalk

Part Number: HD3SS3202

Tool/software:

Hello

I do have 2 questions:

1. do we have a device similar to HD3SS3202, however, with better crosstalk?

2. how is crosstalk in the datasheet defined / measured?

Thanks and regards

Alex

    Hi Alex:

         for Q1: it looks HD3SS3202 has best crosstalk at 5Ghz for our devices.

         For Q2: crosstalk is a measure of the unwanted signal that is coupled through from one channel to another

           for crosstalk, A0B0 is on, crosstalk  is measured from A0 to B1.

      Let me know if you have more questions.

    Regard's

    from customer :Below block diagram is how they wanna try it out and do have the following questions:

    • Is it sufficient to have only AC-coupling Cs at one stage
    • Can they leave unused PINs floating or can this cause any oscillation?

    yes, AC cap is only needed on one side.

    for unused channel, it's better to  connect to 100nf and 50 ohm to gnd. to get better crosstalk.
