Hi TI,

I'd like to use this device as a AUX buffer. So I will use AUXA and AUXC signal pin only at this time.

I'd like to know how to terminate below unused pins;

DAz,DBz,DCz,

HPDA,HPDB, HPDC,

AUXB,

DDCCLK_x, DDCDAT_A

If you only plan to use AUX function, would you please take a look at this to see if this is a better fit? www.ti.com/.../ts3usbca4.pdf.

Thanks

David,

thank you for your help but your suggested device(TS3USBCA4) is still under development.

We(my customer) already started to design a system with HD3SS215. (Plan to use this device as DP buffer, too)

Could you please let me know the recommended termination method of unused pins ?

Are you looking for AUX to AUX buffer that can boost AUX signal? I am sorry I did not initially catch this. The HD3SS215 is just a passive switch, it will not boost the AUX signal, same goes for the TS3USBCA4.

Thanks

David, thanks.

Yes I know this is just passive switch. I don't need boost the signal, just need switch.

Please let me know How to handle the unused pins ?

Since this is a switch, unused pins can be leave floating.

Thanks
