Overview
The UXN14M9P/TR is a programmable integer divider and prescaler manufactured by Microchip Technology. It supports frequency ranges from 0 Hz to 14 GHz with divide ratios between 8 and 511. The device operates at a single supply voltage of 3.3 V and features single-ended or differential inputs. It is housed in a 40-pin QFN (6x6 mm) package with an exposed pad for thermal management.
Feature Summary
- Supports programmable integer division ratios ranging from 8 to 511
- Operates up to 14 GHz input frequency
- Accepts single-ended or differential signal inputs
- Designed for use in fractional and integer N frequency synthesizers
Applications
- Fractional-N frequency synthesizer architectures
- Integer-N frequency synthesizer architectures
- Wireless communication systems requiring high-frequency division
- Test and measurement equipment operating in RF domains
Procurement Notes
Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the 40-QFN package dimensions match the design footprint. Ensure the 3.3V supply requirement aligns with the system power rails. Check RoHS compliance status if required by environmental regulations.
Selection Notes
Select this component when a wide tuning range and high maximum frequency are required within a compact surface-mount form factor. The ability to accept differential inputs provides flexibility in interface design. Consider the thermal performance of the exposed pad for PCB layout optimization.
Part Context
This part belongs to Microchip's family of RF prescalers and dividers. It serves as a critical stage in frequency synthesis chains, allowing for precise frequency generation by dividing high-frequency reference signals. It complements other components like mixers and VCOs in complete synthesizer solutions.
Replacement Considerations
The UXN14M9P/TR is functionally equivalent to the UXN14M9P. Verify that any substitute maintains the 14 GHz maximum frequency and 8-511 divide ratio specifications. Ensure pin compatibility and package size match the existing board layout.
