TPS65987DDJ: USB compliance testing

David Mckinney

Part Number: TPS65987DDJ

Can you advise if there are any special conditions required to perform USB compliance testing with the TPS65987DDJ? We previously have had good results with the TPS65987DDH But have not been able to get the USB compliance testing patterns to operate with the "J" device. Please advise.

Hi David,

I don't believe so there's any special requirement but I will check with the team and get back to you next week regarding any conditions for USB compliance.

Thank you,

Hari

Discovered USB test complaince fixture had BOTH jumpers that connect VBUS-to-CC1 and VBUS-to-CC2... set at the same time. From USB-IF (page 9), noted that Vconn signal must not traverse end-to-end through the cable / fixture. So the jumper on one must be removed and the other remain placed. Thank you and please close this E2E post.
