Rev. 2.0.0
internally generated jitter is a function of the PLL
bandwidth, which in turn is a function of the input 1s
density. For higher 1s densities, the amount of gener-
ated jitter decreases. Generated jitter also depends on
the quality of the power supply bypassing networks
used. Figure 8 shows the suggested bypassing net-
work, and Table 3 lists the typical generated jitter
performance achievable with this network.
