Phase - Frequency Detector, Differential, ECL, 3.3 V / 5.0 V

Favorite

Overview

The MC100LVEL40 is a three state phase frequency-detector intended for phase-locked loop applications which require a minimum amount of phase and frequency difference at lock. Advanced design significantly reduces the dead zone of the detector. For proper operation, the input edge rate of the R and V inputs should be less than 5 ns. The device is designed to work with a 3.3 V 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.

The VBB pin, an internally generated voltage supply, is available to this device only. For single-ended input conditions, the unused differential input is connected to VBB as a switching reference voltage. VBB may also rebias AC coupled inputs. When used, decouple VBB and VCC via a 0.01 5F capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBB should be left open.

For application information, see AND8040/D, "Phase Lock Loop Operation."
