MC12080DR2G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC12080DR2G is a high-speed RF prescaler from onsemi's MC12080 series, designed for frequency division in radio frequency applications. It operates within a frequency range of 100 MHz to 1.1 GHz and provides divide-by-10, -20, -40, or -80 ratios via external logic inputs. The device functions on a single 5V supply with a typical current consumption of 3.7 mA. It features an ECL-compatible output swing of approximately 1.2 V. Packaged in an 8-pin SOIC surface-mount format, it supports operation between -40°C and +85°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Package: Available in an 8-lead Small Outline Integrated Circuit (SOIC) package.

Clock Generators, PLLs, Frequency Synthesizers Applications

• Local Oscillator chains in communication systems
• Frequency synthesizers requiring high-frequency division
• RF test and measurement equipment

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'DR2G' against the manufacturer datasheet to confirm reel packaging and lead-free status. Ensure the design accommodates the 5V supply requirement and ECL-level output voltage swings. Confirm thermal management requirements for the SOIC package within the specified operating temperature range.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a divide-by-10/20/40/80 prescaler is required for frequencies up to 1.1 GHz. Compare with the MC12093 if lower power consumption or standby modes are needed, as the MC12093 offers divide-by-2/4/8 options. Ensure the system interface matches the ECL output characteristics provided by the MC12080.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MC12080 belongs to onsemi's family of high-speed prescalers. It is often used in conjunction with counters or dividers to extend the frequency range of phase-locked loops (PLLs). The DR2G designation indicates the tape-and-reel packaging variant of the standard MC12080DG.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The MC12093 is a related low-power alternative offering divide-by-2, 4, and 8 ratios. Verify pin compatibility and logic control requirements before substitution, as the division ratios differ significantly.
