The Stratix IV device family supports LVDS on both row and column I/O banks. Row
I/Os support true LVDS input with 100-Ω differential input termination (OCT R
and true LVDS output buffers. Column I/Os supports true LVDS input buffers
without OCT R
emulated LVDS output buffers that use two single-ended output buffers with an
external resistor network to support LVDS, mini-LVDS, and RSDS standards.
Stratix IV devices offer single-ended I/O refclk support for the LVDS.
Dedicated SERDES and DPA circuitries are implemented on the row I/O banks to
further enhance LVDS interface performance in the device. For column I/O banks,
SERDES is implemented in the core logic because there is no dedicated SERDES
circuitry on column I/O banks.
Emulated differential output buffers support tri-state capability starting with the
Quartus II software version 9.1.
