Interleaved operation using two ADP1047 or ADP1048

Hi there:

On the datasheet it says the SYNC pin could be used to implement interleaved PFC with multiple ADP1047 or ADP1048 (at the PWM FREQUENCY SYNCHRONIZATION section).

To my comprehension, I would need to connect a source clock to both SYNC pin and manually adjust PWM settings in the GUI to make the phases of multiple ADP1047 or ADP1048 interleaved?
