3.5.1 PLL

The PLL blocks of F280013x/15x and F28P55x devices are the same, however the maximum PLL Raw Clock for F28P55x is higher to accommodate the SYSCLK frequency requirement of F28P55x. Table 3-4 lists the PLL features for both devices for comparison. for more information, consult the TMS320F28P55x microcontrollers technical reference manual.
