UXN14M9P

Overview

The UXN14M9P is a highly programmable integer divider manufactured by Microchip Technology, designed for high-frequency applications. It covers all integer divide ratios between 8 and 511, functioning as a prescaler in frequency synthesis systems. The device supports a maximum operating frequency of 14 GHz with a minimum of 0 Hz. It operates on a single supply voltage of 3.3 V and is rated for an operating temperature range from -40°C to +125°C. The component is housed in a compact 40-QFN (6x6) package with exposed pad, suitable for surface-mount assembly.

Feature Summary

• Supports programmable integer division ratios ranging from 8 to 511
• Features single-ended input and output configurations
• Capable of operation up to 14 GHz frequency
• Designed for use in fractional and integer-N frequency synthesizers

Applications

• Fractional-N frequency synthesizer architectures
• Integer-N frequency synthesizer architectures
• High-speed clock distribution networks
• RF communication system local oscillators

Procurement Notes

Verify the specific ordering suffix when purchasing, such as /TR for tape and reel packaging, to ensure compatibility with automated surface-mount assembly processes. Confirm that the 3.3V supply requirement aligns with the target system design. Check the latest datasheet for any updates regarding moisture sensitivity levels or recommended soldering profiles to maintain component integrity during manufacturing.

Selection Notes

Select this component when a wide division ratio range is required within a single integrated circuit for high-frequency signal processing. The 40-QFN package offers a small footprint beneficial for space-constrained designs. Ensure the application environment stays within the specified -40°C to +125°C temperature range to guarantee reliable performance and longevity of the device.

Part Context

This part belongs to the UXN14M9 family of programmable prescalers from Microchip Technology. These devices are engineered to provide flexible frequency division capabilities for complex RF front-end designs.
