Part Number: TUSB211

Hi team,

My customer wants to use TUSB2XX with pre-channel via PCB trace and post-channel via USB cable.

Could you please let me know the maximum supported FR4 trace length of TUSB2xx?

The table1 on SLLA392 has mixed description with FR4 and AWG.

How can I translate it from AWG length into FR4 length?

Regards,

Itoh

The is no direct correlation between cable gauge/length and PCB trace length. USB cable tend to have much more loss than PCB trace. Can you give me an idea of the system you want to achieve and I can provide recommendation from there?
