Is PLL cascading supported for Cyclone® IV GX device transceivers? - Is PLL cascading supported for Cyclone® IV GX device transceivers? Description No, you cannot cascade the PLLs when used for transceivers. Quartus® II version 10.0 Service Pack 1 and earlier may not restrict such implementation, but PLL cascading is not supported when the PLL is used for the transceiver. Resolution Refer to the "Cyclone® IV Transceivers Architecture" chapter of the Cyclone IV Handbook for supported PLL/clocking configurations.
