9.2.3 Application Curves

The low additive noise of the LMK1D2108. The low noise 156.25-MHz source with 25-fs RMS jitter, shown in Figure 9-3, drives the LMK1D2108, resulting in 46.9-fs RMS when integrated from 12 kHz to 20 MHz (Figure 9-4). The resultant additive jitter is a low 39.7-fs RMS for this configuration. Note that this result applies to the LMK1D2106 device as well.
