Is quartz frequency 16MHz possible with usb usage ?

Have to design new Hardware with SAMA5D34 or SAMA5D36.
The datasheet tells me at some pages a recommended oscillator/clock frequency of 12/16/24/48MHz and in other pages is recommended to use 12MHz to use USB. I would prefer to use 16MHz, because we have this in our stock. Are there any issues to use USB with that frequency? Why is 12MHz recommended?
