HMC983LP5ETR

Overview

The HMC983LP5ETR is a prescaler and fractional-N divider integrated circuit manufactured by Analog Devices Inc. It operates from DC to 7 GHz and functions as a frequency sweeper. The device is housed in a 32-pin QFN package (LFCSP-32) suitable for surface mount technology. It supports a supply voltage range of 4.75 V to 5.25 V, with a typical operating voltage of 5 V. The component is rated for an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates prescaler and fractional-N divider functionality within a single chip
• Capable of operation across a wide frequency range from DC to 7 GHz
• Includes built-in frequency sweeping capabilities for system testing

Applications

• Direct conversion receivers requiring high-frequency downconversion
• Frequency synthesizer architectures utilizing fractional-N loops
• Test and measurement equipment needing programmable frequency sources

Procurement Notes

Verify current availability status through authorized distributors, as the component may be subject to limited supply or end-of-life conditions. Confirm that the specific ordering suffix matches the required package and tape/reel specifications. Ensure compatibility with the target PCB footprint and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when a combined prescaler and divider solution is required for frequencies up to 7 GHz. Consider the 32-QFN package size for space-constrained designs. Evaluate the power consumption against system budget constraints, noting the 5 V supply requirement. Verify that the frequency sweep feature aligns with the specific testing or synthesis needs of the application.
