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 the
MC12147, MC12148 or MC12149 VCO, a high bandwidth PLL can be
realized. The device is functionally compatible with the MC12040
phase-frequency detector, however the MOSAIC III process is used to
push the maximum frequency to 800 MHz and significantly reduce the dead
zone of the detector. 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.

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
MECL10H logic levels while the MCK12140 is compatible to 100K ECL
logic levels. This device can also be used in +5.0 V systems. Please refer to
Motorola Application Note AN1406/D, “Designing with PECL (ECL at +5.0
V)” for more information.

• 800 MHz Typical Bandwidth

• Small Outline 8-Lead SOIC Package

• 75 kΩ Internal Input Pulldown Resistors

• >1000 V ESD Protection

For proper operation, the input edge rate of the R and V inputs should be
less than 5ns.

APPLICATIONS INFORMATION

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 ±2π radians.

The operation of the 12140 can best be described using
the plots of Figure 1. Figure 1 plots the average value of U

, D
and the difference between U and D versus the phase
difference between the V and R inputs.

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:

R lags V in phase

When the R and V inputs are equal in frequency and the
phase of R lags that of V the U
D

output will pulse from HIGH to LOW. The magnitude of the

output will stay HIGH while 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
VCO to decrease in frequency to bring the loop into lock.

V frequency > R frequency

When the frequency of V is greater than that of R the
12140 behaves in a simlar fashion as above. Again the signal
on D

indicates that the VCO frequency must be decreased to

bring the loop into lock.

R leads V in phase

When the R and V inputs are equal in frequency and the
phase of R leads that of V the D
the U

output pulses from HIGH to LOW. The magnitude of the

output will stay HIGH while

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
VCO to increase in frequency to bring the loop into lock.

V frequency < R frequency

When the frequency of V is less than that of R the 12140
behaves in a simlar fashion as above. Again the signal on U
indicates that the VCO frequency must be decreased to bring
the loop into lock.

From Figure 1 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.
