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.
More information on Phase Lock Loop operation and application can
be found in AND8040.
The pinout is shown in Figure 1, the logic diagram in Figure 3, and
the typical termination in Figure 5.
