Cyclone IV GX devices contain up to eight general purpose PLLs and multipurpose
PLLs while Cyclone IV E devices have up to four general purpose PLLs that provide
robust clock management and synthesis for device clock management, external
system clock management, and high-speed I/O interfaces.
For more information about the number of general purpose PLLs and multipurpose
PLLs in each device density, refer to the
The general I/O pins cannot drive the PLL clock input pins.
