USB Hosts Hubs Transceivers

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)

U3RXVDDQ  and U3TXVDDQ are needed to power up the USB 3.0 related blocks. If you do not need 3.0 connectivity, you can leave it open
