Figure 6–4. Cyclone III Device Family On-Chip Series Termination with Calibration Setup
RUP and RDN pins go to a tri-state condition when calibration is completed or not
running. These two pins are dual-purpose I/Os and function as regular I/Os if you
do not use the calibration circuit.
The Cyclone III device family supports driver impedance matching to the impedance
of the transmission line, which is typically 25 Ω or 50 Ω. When used with the output
drivers, OCT sets the output driver impedance to 25 Ω or 50 Ω. The Cyclone III device
family also supports I/O driver series termination (R
SSTL-18.
