December 2010 Altera Corporation
Arria II devices feature OCT to provide I/O impedance matching and termination
capabilities. OCT maintains signal quality, saves board space, and reduces external
component costs.
Arria II devices support the following features:

Arria II devices support OCT in all user I/O banks by selecting one of the OCT I/O
standards. Arria II devices support OCT in the same I/O bank with different I/O
standards if they use the same VCCIO supply voltage. You can independently
configure each I/O buffer in an I/O bank to support OCT or programmable current
strength. However, you cannot configure both R
strength for the same I/O buffer.
A pair of RUP and RDN pins are available in a given I/O bank for Arria II GX
series-calibrated termination and shared for Arria II GZ series- and parallel-calibrated
termination. RUP and RDN pins share the same V
I/O bank where they are located. RUP and RDN pins are dual-purpose I/Os, and
function as regular I/Os if you do not use the calibration circuit.

Arria II 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, you can significantly reduce reflections. Arria II devices support
