MCK12140数据手册集成电路（IC）的时钟发生器PLL频率合成器规格书PDF

描述 Description

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.
