ISOUSB211: About USB Data Connections

Hi team,

Regarding the USB data signals D±, would it be okay to connect D- to DD+/UD+ and D+ to DD-/UD-?

Due to PCB layout constraints, we would like to reverse the polarity of the connected signals.

Best Regards,
Ryu.

Hi Ryu,

Thanks for reaching out.

Unfortunately, NO.

D+ and D- cannot be reversed neither on UD nor on DD side.

There will be functionality failure if the D+ and D- are reversed for ISOUSB211.

Varun
