Although data rates for next generation serial busses typically double the information
capacity of the previous generation, costs are not allowed to double. Use of low-cost
components, specifically reference clocks and integrated VCO’s, places significant
burdens on the PLL and DLL circuitry in system transmitters and receivers. This paper
will examine how the design and performance of the various elements of a system (clocks,
PLL’s, DLL’s etc.) interact with each other and eventually contribute to the overall
system jitter budget.
