What the Dual-Dirac Model is and What it is Not

The dual-Dirac model is a simple tool for estimating total jitter defined at a bit error ratio, TJ(BER), for serial data components and systems. By virtue of the fact that it can be used to combine the RJ and DJ of different elements to predict the TJ(BER) for a system, the dual-Dirac model is a key tool in specifications for serial data links. In this paper, we present the dual-Dirac model, how and why it is used in specifications, how it is used to estimate the Total Jitter of a system, the assumptions it makes and where they fail.
