Stratix GX Device Handbook, Volume 1
Slew-Rate Control
The output buffer for each Stratix GX device I/O pin has a programmable
output slew-rate control that can be configured for low-noise or high-
speed performance. A faster slew rate provides high-speed transitions for
high-performance systems. However, these fast transitions may
introduce noise transients into the system. A slow slew rate reduces
system noise, but adds a nominal delay to rising and falling edges. Each
I/O pin has an individual slew-rate control, allowing you to specify the
slew rate on a pin-by-pin basis. The slew-rate control affects both the
rising and falling edges.
Bus Hold
Each Stratix GX device I/O pin provides an optional bus-hold feature.
The bus-hold circuitry can weakly hold the signal on an I/O pin at its last-
driven state. Since the bus-hold feature holds the last-driven state of the
pin until the next input signal is present, an external pull-up or pull-down
resistor is not needed to hold a signal level when the bus is tri-stated.
Table 4–25
The bus-hold circuitry also pulls undriven pins away from the input
threshold voltage where noise can cause unintended high-frequency
switching. You can select this feature individually for each I/O pin. The
bus-hold output drives no higher than V
signals. If the bus-hold feature is enabled, the programmable pull-up
option cannot be used. Disable the bus-hold feature when using open-
drain outputs with the GTL+ I/O standard or when the I/O pin has been
configured for differential signals.
