Zero-Delay Buffer Mode
In ZDB mode, the external clock output pin is phase-aligned with the clock input pin
for zero delay through the device. When using this mode, you must use the same I/O
standard on the input clocks and output clocks to guarantee clock alignment at the
input and output pins. ZDB mode is supported only on the center and corner PLLs in
Stratix V devices.
When using Stratix V PLLs in ZDB mode, along with single-ended I/O standards, to
ensure phase alignment between the CLK pin and the external clock output (CLKOUT)
pin, you must instantiate a bi-directional I/O pin in the design to serve as the
feedback path connecting the FBOUT and FBIN ports of the PLL. The PLL uses this
bidirectional I/O pin to mimic, and compensate for, the output delay from the clock
output port of the PLL to the external clock output pin.
The bidirectional I/O pin that you instantiate in your design must always be assigned
a single-ended I/O standard.
To avoid signal reflection when using ZDB mode, do not place board traces on the
bi-directional I/O pin.
