Internal Phase-Locked Loop (IPLL)
•
Phase-locked-loop clock frequency multiplier
— No external components required
— Reference divider and multiplier allow large variety of clock rates
— Automatic bandwidth control mode for low-jitter operation
— Automatic frequency lock detector
— Configurable option to spread spectrum for reduced EMC radiation (frequency modulation)
