What should engineers review before using UXN14M9P?

Review the -3.3 V supply arrangement, CML input and output bias requirements, 50 ohm RF terminations, package paddle connection to Vcc, divide-ratio-dependent duty cycle, and control-update timing for dynamically programmed operation.

What is the pinout of UXN14M9P?

Use the UXN14M9P datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about UXN14M9P pinout to locate pins, power rails, and interface signals before layout.

AI summary

UXN14M9P is a programmable high-frequency integer divider for divide ratios from 8 to 511 and input frequencies up to 14 GHz.

Best for

High-frequency PLL frequency division
Integer-N synthesizers
Fractional-N synthesizers using dynamic divide control

Avoid if

A guaranteed 50% output duty cycle is required across all divide ratios
A currently active lifecycle part is mandatory without qualification review

Check before use

Verify discontinued lifecycle status with the supplier
Confirm input amplitude and common-mode voltage remain within CML limits
Confirm output DC return path or AC-coupled bias tee design
Check control timing when changing the divide ratio dynamically
