Stratix III OCT
Dynamic OCT
Stratix III devices support on-off dynamic series and parallel termination for a
bi-directional I/O in all I/O banks.
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.
You should connect a bi-directional pin that uses both 25-Ω or 50-Ω series termination
and 50-Ω input termination to a calibration block that has a 50-Ω external resistor
connected to its RUP and RDN pins. The 25-Ω series termination on the bi-directional
pin is achieved through internal divide by two circuits.
