f
Stratix devices implement differential on-chip termination to reduce
reflections and maintain signal integrity. On-chip termination also
minimizes the number of external resistors required. This simplifies
board design and places the resistors closer to the package, eliminating
small stubs that can still lead to reflections.
R
Stratix devices support differential on-chip termination for the LVDS I/O
standard. External termination is required on output pins for PCML
transmitters. HyperTransport, LVPECL, and LVDS receivers require
100 ohm termination at the input pins.
differential termination for the LVDS I/O standard.
