MCH12140_06 Datasheet, PDF (1/5 Pages) ON Semiconductor – Phase-Frequency Detector

MCH12140, MCK12140
Phase-Frequency Detector
Description
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 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 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 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
Features
• 800 MHz Typical Bandwidth
• Small Outline 8-Lead SOIC Package
• 75 kW Internal Input Pulldown Resistors
• >1000 V ESD Protection

For proper operation, the input edge rate of the R and V inputs
should be less than 5.0 ns.
