MC12093MNR4G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC12093MNR4G is a single modulus prescaler utilizing MOSAIC V technology for low-power frequency division of high-frequency input signals up to 1.1 GHz. It operates on a supply voltage ranging from 2.7 V to 5.5 V, with typical current consumption of 3.0 mA and power dissipation of 6.75 mW at minimum voltage. The device features divide ratios of ÷2, ÷4, or ÷8 selected via SW1 and SW2 pins. An integrated standby mode reduces current drain to approximately 120 µA when the SB pin is LOW. On-chip output termination drives a 2.0 pF load, supporting ECL outputs.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix 'MNR4G' corresponds to the DFN8 package and tape & reel shipping configuration containing 1000 units. Confirm RoHS compliance and Pb-Free status as specified in the datasheet attributes. Ensure the application environment remains within the -40°C to +85°C operating temperature range.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component for applications requiring a single modulus prescaler with toggle frequencies up to 1.1 GHz. The DFN8 package is suitable for surface mount designs where space efficiency is required. Consider external parallel resistance if the internal termination cannot drive the specific load capacitance requirements of the downstream circuitry.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MC12093 family of low-power prescalers. The MC12093MNR4G specifically denotes the version packaged in an 8-lead DFN (DFN8) case, designated as CASE 506AA. Other variants in the series include the SOIC-8 NB package options such as MC12093DG and MC12093DR2G.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include MC12093DG and MC12093DR2G, which share identical electrical characteristics but differ in packaging (SOIC-8 NB vs. DFN8). Verify pinout compatibility and thermal management requirements when substituting between package types.

Clock Generators, PLLs, Frequency Synthesizers FAQ

How is the divide ratio determined?

The divide ratio is set by the logic states of the SW1 and SW2 pins. H-H selects ÷2, H-L or L-H selects ÷4, and L-L selects ÷8.

What is the function of the Stand-By (SB) pin?

Driving the SB pin LOW (GND to 0.8 V) disables the prescaler, reducing the supply current to a typical standby value of 120 µA.

Can the output drive capability be increased?

Yes, an external resistor can be added in parallel from the OUT pin to GND to increase output power, provided the maximum allowable output current of 4.0 mA is not exceeded.
