Figure 96. Effect of PFD (REF_CLK) Frequency on PLL Phase Noise
Another example is shown below where a trade-off can be made between close-in phase noise and far-end phase noise by adjusting the
loop filter bandwidth. As stated previously the higher the loop filter bandwidth, the better the close-in noise but with the scarification of
the far-end noise, and vice versa.
