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 under- shoot 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 result- ing in reduced noise immunity. For these reasons, Schottky diodes are often recommended for termina- tion.
Applications
Reduce overshoots and undershoots on high speed data lines C016097D SCHEMATIC CONFIGURATION 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.
