USB high-speed disconnect

Chikku

Hi Forum,

Regarding the USB high-speed disconnect detection threshold VHSDSC.
The DM6446 eratta pg 18(Advisory 2.1.27), says that some Electrical Parameters Violate USB Specification
and design your system accordingly.

Does anybody has more details about this issue, what exactly should I modify and does it require any circuit redesign.

Thankyou and Regards.

Based on our experience this issue has not impacted the USB functionality on DaVinci. No modifications were required

Hi swami,

Thankyou very much for the information,

I understood that this issue has no impact on the USB functionality.
As I don't know much about the USB compliance test specification,
I thought this eratta(Violation with USB Specification) would cause problem
with USB compliance test.
Please let me if there are any other issues related to USB.

Thankyou.
