CALIFORNIA MICRO DEVICES

Schottky Diode Network

PDN001

Features

• Highly effective termination on controlled
and uncontrolled line impedances

• 18 terminating lines/package

• Saves board space and component cost

Product Description

Reflections on high speed data lines lead to under­shoot and overshoot disturbances which may result in
improper system operation. Resistors, when used to
terminate these high speed data lines, increase power
consumption and degrade the output high level result­ing in reduced noise immunity. For these reasons,
Schottky diodes are often recommended for termina­tion.

SCHEMATIC CONFIGURATION

Applications

• Reduce overshoots and undershoots on
high speed data lines

CAMD’s PDN001 Schottky Diode minimizes the
overshoots and undershoots and provides effective
termination of high speed data lines under variable
loading conditions.

Note: The PDN001 has been improved and is available as an
upgraded device — PACDN005. The PACDN005 is recommended
for all new designs.
