Abstract

In this paper, a thorough analysis of the jitter behavior of a Delay Locked Loop (DLL) based clock multiplying architecture is presented. The noise sources that are included in the analysis are the noise of the delay elements, the reference jitter and the noise of the Phase Frequency Detector and Charge Pump combination. It is shown that the effect of all noise sources on the output timing jitter can be minimized by minimizing the loop gain of the DLL. This means that the loop is merely used to tune the delay of the Delay Line to a nominal value of exactly one reference input period; the loop is ineffective in filtering jitter. The analysis results are verified using high-level simulations, with good agreement.
