RJ/DJ jitter decomposition technique for high speed links

Abstract

With the continuously increasing demand for higher bandwidth, bit rates of high speed serial links (USB, SATA, PCI-express, etc.) have reached the multi-gigabits per second. The transmitted jitter at a given bit error rate is one of the major electrical parameters used to characterize SerDes Integrated Circuit performance. The standard organizations specify RJ and DJ budgets. Decomposing the jitter into random and deterministic jitter would help designers to achieve desired Figure of Merit for future SerDes versions. We extend in this paper our previous technique [1] for jitter analysis and decomposition, in order to be used for any kind of noise profiles (white and colored noise profiles). Jitter decomposition simulations on generated white and colored noise patterns verify the extended decomposition algorithm works properly.
