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

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.

Is it sufficient to have only AC-coupling Cs at one stage

yes, AC cap is only needed on one side.

Can they leave unused PINs floating or can this cause any oscillation?

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