Product details

RF local oscillator with integrated VCO

The Texas Instruments LMX2531LQ2080E/NOPB is a PLL-based frequency synthesizer with an on-chip VCO, generating local oscillator signals up to 2.274 GHz. It accepts a clock input and delivers a CMOS output.

Temperature grade and deployment environment

Rated for -40°C to 85°C, this synthesizer suits outdoor telecom cabinets, base station remote radio heads, and industrial RF test gear. It is not qualified for extended military or downhole environments. The industrial range covers the thermal cycling typical of uncontrolled shelters and rooftop installations without requiring active cooling.

Lifecycle and sourcing posture

Listed as Active with ROHS3 compliance. No last-time-buy notice or obsolescence risk for new designs. The NOPB suffix indicates lead-free / RoHS-compliant finish — verify your assembly house's reflow profile for Pb-free solder.

Frequently asked questions

Is LMX2531LQ2080E/NOPB compatible with 3.3V logic?

The supply range is 2.8V to 3.2V, so a 3.3V rail is within tolerance. However, the VCO's phase noise and pulling performance are optimized for a clean 2.8V–3.2V supply — a noisy 3.3V rail may degrade close-in phase noise. Use a low-noise LDO to feed this part.
