Figure 6–5. Cyclone III Device Family On-Chip Series Termination Without Calibration
All I/O banks and I/O pins support impedance matching and series termination.
Dedicated configuration pins and JTAG pins do not support impedance matching or
series termination.
On-chip series termination is supported on any I/O bank. V
compatible for all I/O pins to enable on-chip series termination in a given I/O bank.

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.

Sheet
The Cyclone III device family supports multiple single-ended and differential I/O
standards. Apart from 3.3-, 3.0-, 2.5-, 1.8-, and 1.5-V support, the Cyclone III device
family also supports 1.2-V I/O standards.
