Stratix devices contain dedicated high-speed PLLs that support differential I/O standards at speeds up to 840 Mbps. You can use these dedicated PLLs to multiply reference clocks and drive high-speed differential SERDES channels. You can instantiate an LVDS receiver megafunction (altlvds_rx) and/or LVDS transmitter megafunction (altlvds_tx) to implement differential I/O standards with a dedicated SERDES.
The following tutorial section teaches you how to use the MegaWizard Plug-In Manager to instantiate an LVDS receiver megafunction in your design.
