I/O Structure & Features

Cyclone II Device Handbook, Volume 1
Cyclone II devices support driver impedance matching to the impedance
of the transmission line, typically 25 or 50 Ω . When used with the output
drivers, on-chip termination sets the output driver impedance to 25 or
50 Ω . Cyclone II devices also support I/O driver series termination
(R
support impedance matching and series termination.

On-chip series termination can be supported on any I/O bank. V
V
termination in a given I/O bank. I/O standards that support different R
values can reside in the same I/O bank as long as their V
not conflicting.

Impedance matching is implemented using the capabilities of the output
driver and is subject to a certain degree of variation, depending on the
process, voltage and temperature. The actual tolerance is pending silicon
characterization.
