Part Number: TS3DV642

Dear Team,

My customer only uses two lanes on TS3DV642 and would like to know how to do for another two lanes.

Should they tie to ground or just leave it floating?

Thank you.

Regards,

Jim

Both are allowed. While I don't think it would make a noticeable difference, it is in general a good idea to have as much ground as possible around high-speed signals.
