Clock
Input
The global or regional clock input can be driven by an output from another PLL or any dedicated CLK or FCLK pin.
It cannot be driven by internally-generated global signals.
In high-speed differential I/O support mode, this high-speed PLL clock feeds the SERDES. Stratix devices only
support one rate of data transfer per fast PLL in high-speed differential I/O support mode.
This signal is a high-speed differential I/O support SERDES control signal.

Clock Multiplication & Division
Stratix device fast PLLs provide clock synthesis for PLL output ports
using m/(post scaler) scaling factors. The input clock is multiplied by the
m feedback factor. Each output port has a unique post scale counter to
divide down the high-frequency VCO. There is one multiply divider, m,
per fast PLL with a range of 1 to 32. There are two post scale L dividers
for regional and/or LVDS interface clocks, and g0 counter for global clock
output port; all range from 1 to 32.
In the case of a high-speed differential interface, set the output counter to
1 to allow the high-speed VCO frequency to drive the SERDES. When
used for clocking the SERDES, the m counter can range from 1 to 30. The
VCO frequency is equal to f
300 and 1000 MHz.
