Order this document By MCH12140/D 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 patible 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 patibility to the two existing ECL standards. The MCH12140 is patible with MECL10H™ logic levels while the MCK12140 is patible 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.
