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
