It integrates the PLL and VCO in a single 36-WQFN (6x6 mm) package with an exposed pad for thermal management. With a maximum output frequency of 2.4 GHz, this device suits RF local-oscillator generation, wireless infrastructure, and test-equipment clocking where a clean, programmable synthesizer is needed. The single-circuit, 2:2 input-to-output ratio allows two clock inputs and two CMOS outputs, though the differential paths are not used here — all signals are single-ended. ## Supply voltage and temperature grade Operating from a 2.8 V to 3.2 V supply rail, the part is compatible with common 3.0 V or 3.3 V logic families, but the 2.8 V minimum means a 2.5 V rail will not do — plan the power tree accordingly. Not qualified to AEC-Q100 — automotive designs require additional screening or a different grade. ## Sourcing and compliance status The /NOPB suffix indicates lead-free (ROHS3 compliant) construction. The part is supplied on Tape & Reel or Cut Tape in the 36-WFQFN package. Availability is confirmed per RFQ; no stock-holding claim is made here.","metaTitle":"LMX2531LQ2265E/NOPB PLL Frequency Synthesizer 2.4 GHz –","metaDescription":"Texas Instruments LMX2531LQ2265E/NOPB PLL frequency synthesizer (RF), 2.4 GHz max, CMOS output, 2.8-3.2 V supply, -40 to 85°C, 36-WQFN.
