Hi CY Friend,

My customer has build a pcb of type c to dp dongle, but the aux and sbu has no signal. HPD  line is 3.3V.

Can you give some suggestions on what we can do?

Thanks

Hi Sophie,

Is this observed even when connected to a Type-C notebook that supports DP and DP configure command is ACK'ed by dongle?

AUX lines are isolated using internal mux by default and connected only on DP configure success.

Regards,

Muthu
