Spread-Spectrum Clocking
PLL Specifications
Cyclone III Device Handbook, Volume 1
f
f
The phasestep signal is latched on the negative edge of scanclk. In
this is shown by the second scanclk falling edge. phasestep must stay high for at
least two scanclk cycles. On the second scanclk rising edge after phasestep is
latched (indicated by the fourth rising edge), the values of phaseupdown and
phasecounterselect are latched and the PLL starts dynamic phase shifting for the
specified counter or counters and in the indicated direction. On the fourth scanclk
rising edge, phasedone goes high to low and remains low until the PLL finishes
dynamic phase shifting. You can perform another dynamic phase shift after the
phasedone signal goes from low to high.
Depending on the VCO and scanclk frequencies, phasedone low time may be
greater than or less than one scanclk cycle. The maximum time for reconfiguring
phase shift dynamically is to be determined (TBD) based on device characterization.
After phasedone goes from low to high, you can perform another dynamic phase
shift. phasestep pulses must be at least one scanclk cycle apart.

The Cyclone III device family can accept a spread-spectrum input with typical
modulation frequencies. However, the device cannot automatically detect that the
input is a spread-spectrum signal. Instead, the input signal looks like deterministic
jitter at the input of the PLL. Cyclone III device family PLLs can track a
spread-spectrum input clock as long as it is in the input jitter tolerance specifications
and the modulation frequency of the input clock is below the PLL bandwidth, which
is specified in the fitter report. The Cyclone III device family cannot generate
spread-spectrum signals internally.
