SCHOTTKYarray™ SERIES
DESCRIPTION
Various configurations of Schottky barrier's diodes in SOT-23 packages are
provided for general-purpose use in high-speed switching, mixers and
detector applications. They may also be used for signal terminations at the
board level. This helps maintain signal integrity and counteract the
transmission-line effects with (PC) board traces 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
impedance is unknown or a variable. This method 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.
