Figure 5-5 is the phase noise plot of the LMKDB1120 output clock as measured by the PNA. The 12 kHz to 20 MHz phase jitter is measured to be 57.2 fs. The PNA measurement is exported as a text file, from which we can import into the Texas Instruments PCIe Reference Clock Analysis Tool in TICS Pro. As PCIe Gen 6.0 requires data from 10 kHz to 50 MHz, the tool estimates the noise floor and extends the data to a full Nyquist band, 50 MHz.
