If the VCO post-scale counter = 2, a 300- to 500-MHz internal VCO frequency is available.
This parameter is limited in the Quartus II software by the I/O maximum frequency. The maximum I/O frequency
is different for each I/O standard.
Cyclone II PLLs can track a spread-spectrum input clock that has an input jitter within ±200 ps.
For extended temperature devices, the maximum lock time is 500 us.

Duty cycle distortion (DCD) describes how much the falling edge of a
clock is off from its ideal position. The ideal position is when both the
clock high time (CLKH) and the clock low time (CLKL) equal half of the
clock period (T), as shown in
non-ideal falling edge from the ideal falling edge, such as D1 for the
falling edge A and D2 for the falling edge B
DCD for a clock is the larger value of D1 and D2.
