AN209 Using Terminator Technology in Stratix & Stratix GX Devices

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 c.
