About this tool
This Excel spreadsheet calculator provides a conservative estimate of output total jitter (TJ) when connecting several elements in series, given each element's jitter contribution in terms of its random (RJ) and deterministic jitter (DJ) components. Alternatively, you can begin with a target output total jitter, then budget jitter to each element in the link to meet this target. In either case, each element's jitter may be tweaked to understand its effect on system performance while optimizing a jitter budget.
Note that this simple calculator makes assumptions that tend to over-estimate the output node's total jitter value. Use it with the intent of revealing potential problems in a system, rather than guaranteeing the system will work trouble-free.
