PLLs 7, 8, 9, and 10 in the EP1S80 device support up to 717-MHz input and output.
Use this equation (f
ranges to determine the allowed PLL settings.
When using the SERDES, high-speed differential I/O mode supports a maximum output frequency of 210 MHz
to the global or regional clocks (that is, the maximum data rate 840 Mbps divided by the smallest SERDES J factor
of 4).
Refer to the section
This parameter is for high-speed differential I/O mode only.
These counters have a maximum of 32 if programmed for 50/50 duty cycle. Otherwise, they have a maximum
of 16.
High-speed differential I/O mode supports W = 1 to 16 and J = 4, 7, 8, or 10.
