MCH12140, MCK12140
Phase-Frequency Detector
Description
The MCH/K12140 is a phase frequency−detector intended for
phase−locked loop applications which require a minimum amount of
phase and frequency difference at lock. When used in conjunction
with high performance VCO such as the MC100EL1648, a high
bandwidth PLL can be realized. The device is functionally compatible
with the MC12040 phase−frequency detector with the maximum
frequency extending to 800 MHz.

MARKING
DIAGRAM
When the Reference (R) and VCO (V) 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. See
AND8040 for further information. The device is packaged in a small
outline, surface mount 8−lead SOIC package. There are two versions
of the device to provide I/O compatibility to the two existing ECL
standards. The MCH12140 is compatible with MECL 10H™ logic
levels while the MCK12140 is compatible to 100 K ECL logic levels.
This device can also be used in +5.0 V systems. See AND8020 for
termination information

APPLICATIONS INFORMATION
R lags V in phase
The 12140 is a high speed digital circuit used as a phase
comparator in an analog phase-locked loop. The device
determines the “lead” or “lag” phase relationship and time
difference between the leading edges of a VCO (V) signal
and a Reference (R) input. Since these edges occur only once
per cycle, the detector has a range of 2p radians.
The operation of the 12140 can best be described using the
plots of Figure 2. Figure 2 plots the average value of U, D
and the difference between U and D versus the phase
difference between the V and R inputs.
When the R and V inputs are equal in frequency and the
phase of R lags that of V the U output will stay HIGH while
the D output will pulse from HIGH to LOW. The magnitude
of the pulse will be proportional to the phase difference
between the V and R inputs reaching a minimum 50% duty
cycle under a 180° out of phase condition. The signal on D
indicates to the VCO to decrease in frequency to bring the
loop into lock.
V frequency > R frequency
There are four potential relationships between V and R: R
lags or leads V and the frequency of R is less than or greater
than the frequency of V. Under these four conditions the
12140 will function as follows:
When the frequency of V is greater than that of R the
12140 behaves in a similar fashion as above. Again the
signal on D indicates that the VCO frequency must be
decreased to bring the loop into lock.

When the R and V inputs are equal in frequency and the
phase of R leads that of V the D output will stay HIGH while
the U output pulses from HIGH to LOW. The magnitude of
the pulse will be proportional to the phase difference
between the V and R inputs reaching a minimum 50% duty
cycle under a 180° out of phase condition. The signal on U
indicates to the VCO to increase in frequency to bring the
loop into lock.

From Figure 2 when V and R are at the same frequency and
in phase the value of U −D is zero thus providing a zero error
voltage to the VCO. This situation indicates the loop is in lock
and the 12140 action will maintain the loop in its locked state.
