USB voltage supply for full/high-speed

Question asked by Mikkel Bjerring on Mar 7, 2019

I have been going over the documentation for the LPC546xx and have a question about the Vdd needed for USB 

this is on page 87 in the datasheet 

 

It is mention that you need a higher voltage to use USB full-speed than the USB high-speed 

any input to why this is the case ?
