Clock Feedback Modes

Set the input pin to the register delay chain in the I/O element to zero in the
Quartus II software for all data pins clocked by a source-synchronous mode PLL.
Also, all data pins must use the PLL COMPENSATED logic option in the Quartus II
software.
In no compensation mode, the PLL does not compensate for any clock networks. This
provides better jitter performance because clock feedback into the PFD does not pass
through as much circuitry. Both the PLL internal and external clock outputs are
phase-shifted with respect to the PLL clock input.

this mode.
Figure 5–9. Phase Relationship Between PLL Clocks in No Compensation Mode
Notes to
(1) Internal clocks fed by the PLL are phase-aligned to each other.
(2) The PLL clock outputs can lead or lag the PLL input clocks.
An internal clock in normal mode is phase-aligned to the input clock pin. The external
clock output pin has a phase delay relative to the clock input pin if connected in this
mode. The Quartus II software timing analyzer reports any phase difference between
the two. In normal mode, the PLL fully compensates the delay introduced by the
GCLK network.
