10.2.3 Application Curves

This section shows the low additive noise for the LMK1D1208P. The low noise 156.25-MHz source with 24-fs RMS jitter shown in Figure 10-2 drives the LMK1D1208P, resulting in 46.4-fs RMS when integrated from 12 kHz to 20 MHz (see Figure 10-3). The resultant additive jitter is 39.7-fs RMS for this configuration.
