Hi Team,
One of my customer would like to use 440nF as AC cap on TX line for their BOM reduction. In general high-speed transmission, I think that there is no problem for using larger capacitance values. But there is a restriction on that value in USB3.1 ECNs.
Can't we use larger capacitance value cap for AC coupling in USB3.1 application and why?
Please let me know if that value is used something in Link up sequence, or if the changing may introduce something issue.
Regards,
Takashi Onawa
