of the device can be shifted by 90° and all 10 DQS pins on the bottom of
the device can be shifted by 72°. The reference circuits require a maximum
of 256 system reference clock cycles to set the correct phase on the DQS
delay elements.

Programmable Drive Strength
The output buffer for each Stratix device I/O pin has a programmable
drive strength control for certain I/O standards. The LVTTL and
LVCMOS standard has several levels of drive strength that the user can
control. SSTL-3 Class I and II, SSTL-2 Class I and II, HSTL Class I and II,
and 3.3-V GTL+ support a minimum setting, the lowest drive strength
that guarantees the I
provides signal slew rate control to reduce system noise and signal
overshoot.
