The MCH12140 or 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.When the Reference (R) and VCO (V) inputs are unequal infrequency and/or phase, the differential UP (U) and DOWN (D)outputs will provide pulse streams which when subtracted andintegrated provide an error voltage for control of a VCO. SeeAND8040 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.

Phase-Frequency Detector; The device is functionally compatible with the MC12040\nphase-frequency detector, however the MOSAIC? III process is used to\npush the maximum frequency to 800MHz and significantly reduce the\ndead zone of the detector. When the Reference (R) and VCO (V) inputs\nare unequal in frequency and/or phase, the differential UP (U) and DOWN\n(D) outputs will provide pulse streams which when subtracted and\nintegrated provide an error voltage for control of a VCO.\nThe device is packaged in a small outline, surface mount 8-lead SOIC\npackage.
