The PLL multiplier can have a max. value of 32 and
the PLLDIV2 can have a min value of 1. So depending on
your input oscillator, you shd be able to achieve
higher clock rate. For eg., 27Mhz Crystal * 31 / 1 =
800Mhz. This is the input to the DDR controller. The
output CLKO is half of that. So 400MHz max.
 Of course you are curtailed if you are using the
VPBE. See sprue14, page 34.
