9.2.3 Application Curves

The low additive jitter of the LMK1C110x-Q1 is shown in Figure 9-2.

Figure 9-3 shows the low-noise 156.25-MHz reference source with 25.6fs RMS jitter driving the LMK1C110x-Q1, resulting in 26.7fs RMS jitter when integrated from 12kHz to 20MHz at 3.3V supply. The resultant additive jitter measured is a low 7.6fs RMS for this configuration.

Figure 9-4 shows the low-noise 156.25-MHz reference source with 25.6fs RMS jitter driving the LMK1C110x-Q1, resulting in 27.5fs RMS jitter when integrated from 12kHz to 20MHz at 2.5V supply. The resultant additive jitter measured is a low 10fs RMS for this configuration.

Figure 9-5 shows the low-noise 156.25-MHz reference source with 25.6fs RMS jitter driving the LMK1C110x-Q1, resulting in 32fs RMS jitter when integrated from 12kHz to 20MHz at 1.8V supply. The resultant additive jitter measured is a low 19.2fs RMS for this configuration.
