From the datasheet "The TUSB422 supports all PD2.0 and PD 3.0 messages except for the PD 3.0 Get Source Capabilities Extended Message"

Hi Michael,

I can only found this in datasheet--
Even though this field defaults to Revision 2.0, the TUSB422 does support some PD 3.0 features like Fast Role swap and chunked extended messages.

BUT, the datasheet still cannot make sure the TUSB422 can support PPS feature(Programmable Power Supply) feature or not. Please double check. Thanks.

The TUSB322 will support basically all of PPS if you do not use the Get Source Capabilities Extended Message. You can look at this reference design for refrence www.ti.com/.../tidudl7.pdf
