Dynamic On-Chip Termination
Stratix III devices support on-off dynamic series and parallel termination
for a bi-directional I/O in all I/O banks.
termination schemes supported in the Stratix III device. Dynamic parallel
termination is enabled only when the bi-directional I/O acts as a receiver
and is disabled when it acts as a driver. Similarly, dynamic series
termination is enabled only when the bi-directional I/O acts as a driver
and is disabled when it acts as a receiver. This feature is useful for
terminating any high-performance bi-directional path because the signal
integrity is optimized depending on the direction of the data.
