UXN14M32K

Overview

The UXN14M32K is a high-performance 32-bit programmable integer divider manufactured by Microchip Technology. It operates within a frequency range of 0 Hz to 15 GHz, supporting division ratios from 1 to 2^32-1. The device is housed in a 24-pin QFN (4x4 mm) surface-mount package and requires a minimum supply voltage of 3.3 V. Designed for RF applications, it functions as a prescaler or superdivider with RoHS compliance.

Feature Summary

• Supports ultra-wide frequency operation up to 15 GHz
• Provides highly programmable integer division ratios up to 2^32-1
• Utilizes a compact 24-pin QFN surface-mount package

Applications

• RF synthesizer feedback loops
• Frequency reference scaling
• High-speed clock distribution networks

Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number UXN14M32K may be available in tape-and-reel formats such as UXN14M32K/TR. Confirm package type and RoHS status directly with the manufacturer or authorized distributors before finalizing procurement orders to ensure compatibility with assembly processes.

Selection Notes

Select this component for designs requiring precise integer division at microwave frequencies. Ensure the input signal amplitude meets the device specifications for reliable operation across the full DC to 15 GHz range. Consider thermal management requirements associated with the QFN-24 package layout during PCB design.
