External Clock Outputs
Each fast PLL supports differential or single-ended outputs for source-
synchronous transmitters or for general-purpose external clocks. There
are no dedicated external clock output pins. Any I/O pin can be driven
by the fast PLL global or regional outputs as an external output pin. The
I/O standards supported by any particular bank determines what
standards are possible for an external clock output driven by the fast PLL
in that bank.
Phase Shifting
Stratix device fast PLLs have advanced clock shift capability that enables
programmable phase shifts. You can enter a phase shift (in degrees or
time units) for each PLL clock output port or for all outputs together in
one shift. You can perform phase shifting in time units with a resolution
range of 125 to 416.66 ps. This resolution is a function of the VCO period,
with the finest step being equal to an eighth (×0.125) of the VCO period.
