Hi,

With customized platform using CYPD-3120 I want to have a USB-C Receptacle instead of plug so that both CC lines are tight. Dongle will have cable flip handling logic based on CC line status.

Can you please let me know(comparing to CYPD-3120 DP reference schematic) how to handle VCONN logic with above scenario?, Do  I need to tight VCONN to CC lines? or any other recommendation. Please suggest.

Thank you,

Hi Arun,

For hardware design, the Type-C receptacle do not have VCONN, only CC1 and CC2. You just need wire CC1 and CC2 from Type-C connector to CC1 and CC2 of CYPD3120 is fine. VCONN of CYPD3120 can be floating.

Best Regards,

Lisa
