Product Description
Reflections on high speed Memory Buses lead to undershoot and overshoot disturbances which may result in improper
system operation. Resistor terminations, when used to terminate high speed memory or data lines, increase power
consumption and degrade output (high) levels resulting in reduced noise immunity. Schottky diode termination is the best
overall solution for applications in which power consumption and noise immunity are critical considerations.
CAMDs P/Active DN010 Schottky Diode Memory Bus Terminator
is specifically designed to minimize undershoot/
overshoot disturbances caused by reflection noise on SDRAM bus lines as well as v2.1 66MHz PCI buses.
This highly integrated Schottky diode network provides very effective termination performance for high speed Memory Bus
lines under variable loading conditions. The packaged device supports up to 18 terminated lines each of which can be
simultaneously clamped to both ground and power supply rail.
Applications
SDRAM Memory Bus Termination
PCI v2.1 Bus Termination for Intel-based Pentium
and Pentium Pro systems
