MC12095MNR4G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC12095MNR4G is a single modulus prescaler utilizing MOSAIC V technology, designed for low power frequency division of high-frequency input signals up to 2.5 GHz. It operates on a supply voltage ranging from 2.7 V to 5.5 V with a typical supply current of 8.7 mA. The device features an internal divide ratio selection via the SW pin, supporting ÷2 or ÷4 ratios. A Stand-By mode reduces current drain to approximately 100 µA when activated. The component includes on-chip output termination suitable for driving high-impedance loads and is housed in a DFN8 package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix 'MNR4G' corresponds to the DFN8 package and Pb-free status as listed in the manufacturer's ordering information table. Confirm that the specific revision of the datasheet matches the production batch requirements. Ensure thermal management considerations are addressed if operating near maximum junction temperatures, noting the thermal resistance specifications for the DFN8 package.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a toggle frequency up to 2.5 GHz is required with minimal power dissipation. The SW pin allows hardware-based selection between divide-by-2 and divide-by-4 modes. Consider the Stand-By function for applications requiring power reduction during idle periods. Ensure the input signal amplitude meets the sensitivity requirements (200–1000 mVpp) across the desired frequency range.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MC12095 is part of the prescaler family from onsemi (formerly Motorola Semiconductor). The 'MNR4G' designation specifically identifies the tape and reel packaging variant in the DFN8 case 506AA footprint. This model succeeds earlier bipolar prescalers, offering improved power efficiency through advanced MOSAIC V technology while maintaining compatibility with standard ECL/CML interface levels.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The MC12093 series offers similar prescaling functions but supports higher divide ratios (÷2/÷4/÷8) and operates up to 1.1 GHz. Verify if the lower frequency limit of the MC12093 meets system requirements. Direct pin-to-pin replacement is not guaranteed due to potential differences in control logic and electrical characteristics; consult respective datasheets for functional equivalence.
