It accepts a clock input and delivers a CMOS output. The part is a PLL frequency synthesizer with integrated VCO, so the lower frequency limit depends on the reference clock and divider settings rather than a specified floor."},{"question":"Is LMX2531LQ1742/NOPB compatible with 3.3V supply?","answer":"Yes, the supply range is 2.8V to 3.2V, which includes a standard 3.3V rail. The 100 mV headroom above 3.2V is tight — the rail should be regulated within ±2% to stay inside the window. A clean 3.3V LDO feeding the part with local decoupling is the typical approach."},{"question":"What is the equivalent part for LMX2531LQ1742/NOPB?","answer":"The CD74HCT7046AE is a through-hole PLL from a different series (74HCT, 38 MHz max, -55°C to 125°C) — not a functional equivalent for RF synthesis at 1.866 GHz. No direct pin-compatible second source is listed in the record. For a dual-source strategy, look at other LMX2531 family variants with the same 36-WQFN footprint and different frequency bands."},{"question":"What is the operating temperature of LMX2531LQ1742/NOPB?","answer":"Rated for -40°C to 85°C, the industrial temperature range. Suitable for outdoor telecom enclosures, base stations, and factory automation where ambient temperatures stay within that span."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMX2531LQ1742-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LMX2531LQ1742-NOPB when reusing this data.
