Honored Contributorconnect two pll in serial to get 250MHZ clock
I have a Cyclone IV E FPGA with a 50MHZ oscillator , since this FPGA cannot generate more than 180 MHZ clock, I decide to get 125MHZ clock from one altpll , using this 125MHZ and then connect to anot...

Honored ContributorPLL can generate directly 250 MHz but your logic should be able to support this frequency, very hard.
