On-Chip Series Termination without Calibration
Stratix II GX devices support driver impedance matching to provide the
I/O driver with controlled output impedance that closely matches the
impedance of the transmission line. As a result, reflections can be
significantly reduced. Stratix II GX devices support on-chip series
termination for single-ended I/O standards with typical R
25 and 50 Ω . Once matching impedance is selected, current drive
strength is no longer selectable.

Characteristics
On-Chip Series Termination with Calibration
Stratix II GX devices support on-chip series termination with calibration
in column I/O pins in top and bottom banks. There is one calibration
circuit for the top I/O banks and one circuit for the bottom I/O banks.
Each on-chip series termination calibration circuit compares the total
impedance of each I/O buffer to the external 25-Ω or 50-Ω resistors
connected to the RUP and RDN pins, and dynamically enables or disables
the transistors until they match. Calibration occurs at the end of device
configuration. Once the calibration circuit finds the correct impedance, it
powers down and stops changing the characteristics of the drivers.
