These dedicated circuits combined, with enhanced PLL clocking and
phase-shift ability, provide a complete hardware solution for interfacing
to high-speed memory.

Programmable Drive Strength
The output buffer for each Stratix II GX device I/O pin has a
programmable drive strength control for certain I/O standards. The
LVTTL, LVCMOS, SSTL, and HSTL standards have several levels of drive
strength that you can control. The default setting used in the Quartus II
software is the maximum current strength setting that is used to achieve
maximum I/O performance. For all I/O standards, the minimum setting
is the lowest drive strength that guarantees the I
Using minimum settings provides signal slew rate control to reduce
system noise and signal overshoot.
