2. The RCD termination
The traditional solution to properly match each line of the bus consists of the use of several discrete
resistances,capacitorsand smallschottkydiodes.For a 16-bitbus, thisrequires48 discretecomponents.

reduces component cost and assembly cost, saves board space and improves
reliability.

The resistorprovidesthe pathterminationfor PCBtrack, thusresulting in low reflectionphenomena.
The capacitor of 33 pF blocks DC currents while acting as a shortcircuit during signal transitions,and

The smallSchottkydiodeclampsthe negativeremainingundershoots whichcan resultfrom impedance
mismatch.This damps negative voltages and preventsthe logic signal from rising above the logic level
’0’ thresholdafter a falling edge.
