                PLL and Transceiver Board Design Guidelines
| Number | Done? | Checklist Item | 
|---|---|---|
| 1 | Connect all PLL power pins to reduce noise even if the design does not use all the PLLs. | |
| 2 | Power supply nets should be provided by an isolated power plane, a power plane cut out, or thick trace of at least 20 mils. | 
Plan your board design when you design a power system for PLL usage and to minimize jitter, because PLLs contain analog components embedded in a digital device.
