DESCRIPTION
Various configurations of Schottky barrier’ s diodes in SOT-23 package are provided for general-purpose use in high-speed switching ,mixers and detector applications. They may also be used for signal integrity and counteract the transmission-line effects with (PC) board trances by clamping over/and undershoot from signal reflections with the schottky-low-threshold voltages.
This type of termination also does not depend on matching the transmission line characteristic impedance, making it particularly useful where line impendance is unknown or a variable. This methode of termination can control distortions of clock, data, address, and control lines as well as provides a stabilizing effect on signal jitter. It can also significantly reduce power consumption compared to standard resistor-based termination methods.
