This chapter describes the hierarchical clock networks and phase-locked loops (PLLs)
with advanced features in the Cyclone
ability to reconfigure the PLL counter clock frequency and phase shift in real time,
allowing you to sweep PLL output frequencies and dynamically adjust the output
clock phase shift.

The Cyclone IV GX device provides up to 12 dedicated clock pins (CLK[15..4]) that
can drive the global clocks (GCLKs). Cyclone IV GX devices support four dedicated
clock pins on each side of the device except the left side. These clock pins can drive up
to 30 GCLKs.
The Cyclone IV E device provides up to 15 dedicated clock pins (CLK[15..1]) that
can drive up to 20 GCLKs. Cyclone IV E devices support three dedicated clock pins
on the left side and four dedicated clock pins on the top, right, and bottom sides of the
device except EP4CE6 and EP4CE10 devices. EP4CE6 and EP4CE10 devices only
support three dedicated clock pins on the left side and four dedicated clock pins on
the right side of the device.
