18.104.22.168. PLL Board Design Guidelines
|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.
