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.
