Use the coarse- and fine-phase shifts to implement clock delays in Arria II GX devices.
The ALTPLL megafunction allows you to enter the desired VCO phase taps and initial
counter value settings through the MegaWizard
software.
Arria II GX devices support dynamic phase-shifting of VCO phase taps only. The
phase shift is reconfigurable any number of times and each phase shift takes about
one scanclk cycle, allowing you to implement large phase shifts quickly.
PLL bandwidth is the measure of the ability of the PLL to track the input clock and its
associated jitter. Arria II GX PLLs provide advanced control of the PLL bandwidth
with the PLL loop’s programmable characteristics, including loop filter and charge
pump. The closed-loop gain 3-dB frequency in the PLL determines the PLL
bandwidth. The bandwidth is approximately the unity gain point for open loop PLL
response.
Arria II GX devices 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. Arria II GX PLLs can track a spread-spectrum input clock as long as
the input jitter is in the PLL input jitter tolerance specification. Arria II GX devices
cannot internally generate spread-spectrum clocks.
