All I/O banks have dedicated circuitry to support the true LVDS, RSDS, and mini-LVDS I/O standards by using true LVDS output buffers without resistor networks.

In Stratix V devices, the LVDS I/O standard requires a 2.5 V VCCIO level. The LVDS input buffer requires 2.5 V VCCPD. The LVDS receiver requires a 100 Ω termination resistor between the two signals at the input buffer. Stratix V devices provide an optional 100 Ω differential termination resistor in the device using RD OCT if VCCPD is set to 2.5 V.

Figure 106. LVDS I/O Standard Termination This figure shows the LVDS I/O standard termination. The on-chip differential resistor is available in all I/O banks.
