PhaseĆFrequency Detector
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 MOSAICIII 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
MECL10Hlogic 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.

NOTE: * This is not strictly a functional table; i.e., it does not cover all possible modes of operation. However, it gives a sufficient number of tests to ensure that
the device will function properly.
