Honored Contributor --- Quote Start --- Can you share a PLL with two DDR2 controllers if you run the two DDR2 banks with the same clock? --- Quote End --- It was possible with the legacy controller. But this is not the case with the ALTMEMPHY controller. It is not possible to use the legacy controller on Cyclone IV devices
