One of my customer, they are using TUSB544 on their tablet project. For some reason, the TUSB544 can not be put very close to the type C socket, the input trace is about 6inchs, and the output trace to the type C socket is about 3~4 inches. which is not meeting our 2 inches recommendation.
As they are using some other vendors similar parts, so they come with some questions:
1. For 5.4Gbps signal, we said the output trace should not be longer than 2inch, can we spec it as how many db insert lost on 5.4Gbps signal?
2, For their simulation, their trace has 4dB insert lost on 5.4Gbps, can TUSB544 support? Since our competitor is saying they can support 3 or 5 dB lost, so they want to compare to see who is better.
