Atmel® AVR® XMEGA® has an advanced clock system, supporting a large number of clock sources. It incorporates both integrated oscillators, and external crystal oscillators and resonators. In addition, an internal high frequency Phase Locked Loop (PLL) can be used to multiply selected clock sources with a factor ranging from 1x to 31x.
