MC100EP140
3.3V ECL Phase−Frequency
Detector
Description
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 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.
