Phase-Frequency Detector

The MC100LVEL40 is a phase/frequency detector intended for

phase–locked loop applications which require a minimum amount of

phase and frequency difference at lock. The device is a basic three state

phase detector with differential inputs and outputs. The device is

designed to work from either a 3.3V or 5.0V power supply.

When the reference (R) and the feedback (FB) inputs are unequal in

frequency and/or phase the differential up (U) and down (D) outputs will

provide pulse streams which when subtracted and integrated provide an

error voltage for control of a VCO.
