PPI Interface Clock in BF537 EZLITE Board

Hello ,
             I am developing a application in which I want to output the
data stored in the SDRAM via PPI Interface.
The data speed must be around 30 MHZ. In other words PPI_CLK needs to be
30 MHz.
I understand that the PPI is clocked through PF15 pin.
I also observed that there is a PPI connector (P8) for PF-15 pin on the
board.

My questions:-
1) How will I clock the PPI interface??
2) Can I clock the PPI with the external clock/source connected to the
"PF15_CAN_STB~" pin in P8.
