TPS2547: About USB certification test at CDP mode

Hi Hideto,

The TPS2547 is USB2.0 and USB3.0 compatible. I would have to go back to the team to is if there are any concerns for specific certification under CDP mode application.

If there are any concerns with this, I'll make sure to let you know.

Dear Yongqiang Sun

How about the TPS2546 can pass the USB certification or not? We got fail about A4.9: Host Test J/K, SE0_NAK (EL_9) in SDP / CDP mode.

SDP mode Test K in D+ is over 20mV and D- is pass. CDP mode Test J in D- is over 20mV and D+ is pass. Do you have any suggestions? Thanks for help~
