implements either a high-speed deserializer receiver or a high-speed serializer
transmitter. There is a list of parameters in the ALTLVDS megafunction that you can
set to customize your SERDES based on your design requirements. The megafunction
is optimized to use Cyclone IV devices resources to create high-speed I/O interfaces
in the most effective manner.
1 When you use Cyclone IV devices with the ALTLVDS megafunction, the interface
always sends the MSB of your parallel data first.
f For more details about designing your high-speed I/O systems interfaces using the
ALTLVDS megafunction, refer to the ALTLVDS Megafunction User Guide and the
Quartus II Handbook.
