SYNTHESIZER CONFIGURATION AND LO OPERATION
Figure 99 shows that the PLL phase noise is highly dependent on the PFD frequency (REF_CLK). A higher PFD frequency achieves a better
phase noise.
Figure 100 shows where a trade off can be made between the close-in phase noise and far-end phase noise by adjusting the loop filter
bandwidth. As mentioned, the higher the loop filter bandwidth, the better the close-in noise but with the scarification of the far-end noise, and
vice versa.
