This section shows the low additive noise for the LMK1D1216. The low noise 156.25-MHz source with 25-fs RMS jitter, shown in Figure 10-2, drives the LMK1D1216, resulting in 46.9-fs RMS when integrated from 12 kHz to 20 MHz (Figure 10-3). The resultant additive jitter is a low 39.7-fs RMS for this configuration. Note that this result applies to the LMK1D1212 device as well.

Note: Reference signal is a low-noise Rhode and Schwarz SMA100B
