3.3VĄECL Phase-Frequency

Detector

The MC100EP140 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. Since the part is designed with fully

differential internal gates, the noise is reduced throughout the circuit,

especially at high speeds. The basic operation of a Phase/Frequency

Detector (PFD) is to “compare” an incoming signal (feedback) to a set

reference signal. When the 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. Detector

states of operation are shown in the Figure 2 and the State Table.

The device is packaged in a small outline, surface mount 8–lead

SOIC package. The typical output amplitude of the EP140 is 400 mV,

allowing faster switching time and greater bandwidth. For proper

operation, the input edge rate of the R and FB inputs should be less

than 5 ns.
