UXN40M7K/TR

Overview

The UXN40M7K/TR is a programmable integer frequency divider (prescaler) manufactured by Microchip Technology. It operates within an input frequency range of 500 MHz to 40 GHz, supporting division ratios from 1 to 127. The device requires a supply voltage between 3 V and 3.6 V, with a typical operating voltage of 3.3 V. It delivers an output power of +2 dBm and exhibits a phase noise figure of -153 dBc/Hz. The component draws 230 mA of operating current and is housed in a 24-pin CQFN package.

Feature Summary

• Supports programmable integer division ratios ranging from 1 to 127 for flexible frequency synthesis applications.
• Operates at high microwave frequencies up to 40 GHz with low phase noise characteristics.
• Designed for surface-mount installation in compact electronic systems.

Applications

• Microwave frequency synthesizers
• Phase-locked loop (PLL) reference dividers
• High-speed clock distribution networks

Procurement Notes

Verify the specific suffix /TR indicates tape-and-reel packaging configuration when ordering. Confirm that the 24-CQFN package matches the target PCB footprint and thermal requirements. Ensure the design accommodates the 230 mA current draw and 3.3 V supply tolerance. Check RoHS compliance status if required for the specific manufacturing region. Validate the lead time against production schedules as availability may vary.

Selection Notes

Select this component when a wideband prescaler covering up to 40 GHz is required. The programmable divide-by-1 to 127 capability allows for versatile integer-N synthesis architectures. Consider the QFN-24 package for space-constrained designs requiring surface-mount technology. Evaluate the -153 dBc/Hz phase noise metric against system sensitivity requirements. Ensure the operating temperature range of -40°C to +85°C aligns with the environmental conditions.
