The Stratix IV GX and GT transmitter buffers includes programmable on-chip
differential termination of 85, 100, 120, or 150 Ω. The resistance is adjusted by the
on-chip calibration circuit in the calibration block (for more information, refer to
“Calibration Blocks” on page
and process changes. The Stratix IV GX and GT transmitter buffers in the transceiver
are current mode drivers. Therefore, the resultant V
termination value. For more information about resultant V

You can disable OCT and use external termination. If you select external termination,
the transmitter common mode is tri-stated. You can set the transmitter termination in
the ALTGX MegaWizard Plug-In Manager.
You can also set the OCT through the Assignment Editor. Set the assignment shown in
Table 1–15
Table 1–15. Stratix IV GX and GT OCT Assignment Settings
The Stratix IV GX and GT devices allow you to customize the differential output
voltage to handle different trace lengths, various backplanes, and receiver
requirements, as shown in
dynamic reconfiguration controller. Set the V
port of the dynamic reconfiguration controller. For example, to set V
set the tx_vodctrl[2:0] to 011.
