MC100LVEL40DWR2G

3.3/5 V ECL 差分 相位-频率检测器

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. pin, an internally generated voltage supply, is available to this device only. For single-ended input conditions, the unused differential input is connected to V as a switching reference voltage. V may also rebias AC coupled inputs. When used, decouple V via a 0.01 5F capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VFor application information, see AND8040/D, "Phase Lock Loop Operation."The 100 Series Contains Temperature Compensation
