Original question:

TUSB422: whether TUSB422 support PD3.0?

TUSB422: Compliant PD3.0 spec

Part Number: TUSB422

Hi team, 

I saw other thread talking about whether the TUSB422 is compliant with PD3.0 or not. Team mentions TUSB422 only cannot support the GetSourceCapExtended message. Is there other feature might be limited? i.e. not able to send GoodCRC for certain message? Please advised. 

Best Regards,

Leroy Song

    Hi Leroy,

    Per the datasheet TUSB422 does not support the GetSourceCapExtended message this mean that TUSB422 will not detect this message and will not send a Good.CRC in reply to the GetSourceCapExtended message. All other PD messages are supported.
