MC12093DR2G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC12093DR2G is a single modulus prescaler utilizing MOSAIC V technology, designed 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 a typical supply current 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 driven LOW. The output includes on-chip termination capable of driving a 2.0 pF load.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Toggle frequency up to 1.1 GHz with input sensitivity of 100–1000 mVpp depending on frequency range
• Low power consumption: 3.0 mA typical supply current; 120 µA typical standby current
• Divide ratio selection (÷2, ÷4, ÷8) controlled by SW1 and SW2 logic inputs
• On-chip output termination drives 2.0 pF load; external resistor can increase drive capability

Clock Generators, PLLs, Frequency Synthesizers Applications

• Frequency synthesizers requiring low-power prescaling
• RF communication systems operating in UHF and microwave bands
• Test and measurement equipment involving signal frequency division

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix DR2G corresponds to the SOIC-8 NB package shipped in a 2500-unit tape and reel configuration. Confirm RoHS compliance and Pb-free status as specified in the datasheet attributes. Ensure the application circuit adheres to the maximum ratings, particularly the 6.0 Vdc absolute maximum supply voltage and 4.0 mA maximum output current limits.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single modulus prescaler is required for frequencies between 100 MHz and 1.1 GHz. The MC12093 is suitable for designs needing specific divide ratios (÷2, ÷4, ÷8) without complex programming. Consider the DFN8 package option if a smaller footprint is necessary, though the DR2G suffix specifically denotes the SOIC-8 variant. Validate input voltage sensitivity requirements against the 100–1000 mVpp ranges provided in the electrical characteristics table.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MC12093 belongs to the MC12093 family of prescalers manufactured by onsemi. The MC12093DG represents the tube-packaged version of the same die, while MC12093MNR4G offers a 1000-unit tape and reel option in the same SOIC-8 package. The DR2G suffix indicates mass production packaging optimized for automated assembly lines.
