I am using AD9467-FMC-250EBZ on Zedboard with an external clock. I want to use the internal clock generator chip AD9517 having phase-locked loop (PLL) to multiply (x4) the externally provided clock (~50 MHz). I can see in the datasheet of AD9517 that there are registers for division but not multiplication. Please tell me whether clock multiplication can be done on AD9517 or not? If not is there any alternative solution for clock multiplication?
