Normal Mode
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 TimeQuest Timing Analyzer reports any phase
difference between the two. In normal mode, the delay introduced by the GCLK or
RCLK network is fully compensated.

Note to
(1) The external clock output can lead or lag the PLL internal clock signals.
Zero-Delay Buffer Mode
In zero-delay buffer (ZDB) mode, the external clock output pin is phase-aligned with
the clock input pin for zero delay through the device. When you use this mode, you
must use the same I/O standard on the input and output clocks to guarantee clock
alignment at the input and output pins. Zero-delay buffer mode is supported on all
Arria II GX PLLs.
