Part Number: TUSB1046A-DCI
Other Parts Discussed in Thread: TUSB1046-DCI,

Hi Teams,

When using the USB 3.1 + 2 Lane Display configuration, the lane of DP 2-3 is unused.

How can I handle terminals? (N.C? Pull-Down?)

Also, is it necessary to invalidate Lane with the DP2-3 register "DP2_DISABLE, DP3_DISABLE"?

Let me know one more thing.

What did you fixed from "TUSB 1046 - DCI" to "TUSB 1046 A - DCI"?

Best Regards,

Kenji

you can leave those two lanes N.C. I am looking into what we fixed from TUSB1046-DCI to TUSB1046A-DCI and will get back to you.

The difference between TUSB1046 and TUSB1046A is the DCI. The TUSB1046A supports DCI and the TUS1046 does not.

Thanks
