LVDS
The LVDS I/O standard is a differential high-speed, low-voltage swing, low-power,
general-purpose I/O interface standard. In Stratix IV devices, the LVDS I/O standard
requires a 2.5-V V
standard in applications requiring high-bandwidth data transfer, such as backplane
drivers and clock distribution. LVDS requires a 100-Ω termination resistor between the
two signals at the input buffer. Stratix IV devices provide an optional 100-Ω
differential termination resistor in the device using on-chip differential termination.
