Hi,

The touchstone model on TI website has quality problem (passivity>1).

Please support to provide new touchstone file or spice model include D+/- to USB+/- and D+/- to MHL+/- performance as soon as possible.

Please let us know if TI can't provide such kind of model immediately and we will change this component to other relay.

Thanks.

Siya

Brian

Yes

Can you try this?

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/138/3000_5F00_s4p.s4p

Passivity is still over 1.

the board was designed long time ago and not works well over 10Ghz.

What freq range you are interested ?
