MOTOROLA SEMICONDUCTOR TECHNICAL DATA Product Preview 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.
