Phase-Frequency Detector
The MCH/K12140 is a phase frequencydetector intended for
phaselocked 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 phasefrequency detector with the maximum
frequency extending to 800 MHz.
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 8lead 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
