HMC859LC3

Overview

The HMC859LC3 is a high-performance prescaler from Analog Devices Inc., designed for frequency division applications. It operates as a divide-by-8 counter with a maximum operating frequency of 26 GHz. The device supports input frequencies ranging from 0 Hz to 26 GHz, enabling versatile use in both low and high-frequency RF systems. It functions on a DC voltage supply of -3.3 V. Key features include an integrated reset function and programmable output voltage capabilities. Constructed using GaAs MMIC technology, it offers low noise performance suitable for millimeter-wave applications.

Feature Summary

• Divide-by-8 frequency division capability
• Integrated reset functionality
• Programmable output voltage
• GaAs MMIC construction

Applications

• Millimeter-wave communication systems

• Test and measurement equipment

Procurement Notes

Verify the specific package type and revision level against the official Analog Devices datasheet before procurement. Confirm that the -3.3 V supply requirement aligns with your system design. Ensure compatibility with the 26 GHz operational limit for your intended application. Check for any specific handling requirements associated with GaAs MMIC components during assembly.

Selection Notes

Select this component when a divide-by-8 prescaler is required up to 26 GHz. Consider the GaAs technology for its low noise characteristics in high-frequency environments. Evaluate the need for the integrated reset feature and programmable output voltage in your circuit design. Compare against other prescalers if different division ratios or frequency ranges are needed.

Part Context

This part belongs to the HMC859 series of prescalers from Analog Devices. It is distinct from similar models like the HMC859LC3TR-R5, which may have different packaging or reel specifications. The LC3 suffix typically denotes a specific lead-free or commercial grade variant within the product line. It serves as a core building block for high-speed digital and RF frequency generation circuits.

Replacement Considerations

Direct substitutes may include other divide-by-8 prescalers from Analog Devices with similar frequency ranges. Verify pinout compatibility and electrical specifications such as supply voltage and current consumption. Cross-reference with the HMC859 family datasheets for functional equivalents.
