【应用手册】Using Differential I/O Standards in MAX V Devices
This application note describes using differential I/O standards in MAX V devices.
High-speed differential I/O standards have become popular in high-speed interfaces
because of their significant advantages over the single-ended I/O standards. The
Altera MAX V device family supports the emulated LVDS output (LVDS_E_3R) and
emulated reduced swing differential signaling (RSDS) output (RSDS_E_3R) I/O
standards using two single-ended outputs and external resistor networks, with the
second output programmed as an inverted output.
