Product details

14 GHz PLL core for RF signal generation

The LMX2492RTWR is a PLL-based frequency synthesizer from Texas Instruments, designed for RF clock and signal generation up to 14 GHz. The PLL architecture locks an internal VCO to a reference clock input, producing a clean output at the target frequency. The 2:1 input-to-output ratio allows selecting between two clock sources, though the part does not support differential signaling on either side. For single-ended clock trees in the 100 MHz to 14 GHz range, this covers most RF local oscillator and test equipment applications.

ROHS3 compliant. The tape-and-reel packaging (Cut Tape also available) suits automated pick-and-place assembly.

Frequently asked questions

What is the maximum output frequency of the LMX2492RTWR?

The LMX2492RTWR supports a maximum frequency of 14 GHz. This is the upper limit of the PLL's output range; the actual locked frequency depends on the reference input and divider settings.

What supply voltage does the LMX2492RTWR require?

A clean 3.3 V rail within ±2% regulation is recommended to avoid injecting noise into the PLL's charge pump and VCO.
