    Welcome to the PF.

    It probably means that you can synchronize the DC-DC converter's switching frequency to an external clock in that frequency range. That is often done to avoid noise interference with other equipment nearby. If you don't supply a synchronizing clock, the DC-DC will free-run at some frequency in that frequency range probably.
