On-chip series termination is supported on any I/O bank. V
must be compatible for all I/O pins to enable on-chip series termination
in a given I/O bank. I/O standards that support different R
reside in the same I/O bank as long as their V
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.
Refer to the DC and Switching Characteristics chapter in volume 2 of the
Cyclone III Device Handbook, for more information about tolerance
specification.
