Using Terminator Technology in Stratix & Stratix GX Devices
November 2002, ver. 2.0 Application Note 209
Introduction
Signal integrity is crucial in high-speed digital designs because of increased system speeds and clock edge rates. Designers must properly terminate single-ended and differential signals to achieve signal integrity. Traditionally, designers use on-board termination resistors to achieve proper signal termination. However, these resistors take up significant board space and can cause signal reflections (stub effects). These reflections normally occur when a termination resistor is too far away from the transmission line it terminates. TerminatorTM technology in StratixTM and Stratix GX devices helps prevent reflections, improving signal integrity.
