TUSB1104: Driving 5M USB 3.1 Gen 2 cable

Hi Joel,

USB3.1 gen 2 is a 10Gbps signal. 

5m may be too long for the TUSB1104. Is the 5m cable a USB compliant cable? What is the loss profile of the cable?

USB specifies no more than 6dB loss for a 1M cable. So 5M meter cable could be up to 30 dB.

An actual cable may be less than that but I could not find any information on loss measured on actual cable.

Hi Joel,

In this case a redriver may not be sufficient for this amount of loss. I recommend looking into retimers for application with high loss like this (20+ dB)

Is there a retimer P/N you can recommend?
