MC100LVEL40
3.3/5V ECL Differential
Phase−Frequency Detector
Description
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 mF capacitor and limit current sourcing or sinking
to 0.5 mA. When not used, VBB should be left open.
For application information, refer to AND8040/D, “Phase Lock
Loop Operation.”
