3.3V / 5V ？ ECL差分相位频率检测 3.3V / 5VECL Differential Phase-Frequency Detector

The 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 / 5 V power supply. When Reference R and 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. When Reference R and Feedback FB inputs are 80 pS or less in phase difference, the Phase Lock Detect pin will indicate lock by a high state. The Vbar pins offer an internal termination network for 50 line impedance environment shown in Figure 2. An external sinking supply of V pins. If you short the two differential Vbar together, you provide a 100 termination resistance that is compatible with LVDS signal receiver termination. For more information on termination of logic devices, see AND8020. 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 F capacitor and limit current sourcing or sinkingto 0.5 mA. When not used, V For more information on Phase Lock Loop operation, refer to AND8040. Special considerations are required for differential inputs under No Signal conditio
