Hi Cypress Community,

I am designing with the Cypress CYUSB3064-BZXC. It is a MIPI to USB high speed converter BGA.

My question is whether or not I need to have +1.2V power on the pins U3TXVDDQ and U3RXVDDQ if I am NOT using the Superspeed USB 3.0.

I currently have both pins set as No Connects since I'm not using USB 3.0, but I see nothing in the datasheet that says if I can do this or if these power pins still need to be powered.

 

Thanks for any help or insight you can give! (datasheet attached)

You can leave U3TXVDDQ  and U3RXVDDQ  open if you are not going to use USB 3.0
