The LMX2541SQ2690E/NOPB carries an Active product status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect. For a BOM line that needs a stable RF source, this part is a safe choice for new designs and ongoing production without near-term obsolescence risk.
The maximum output frequency is 2.865 GHz. The part is a PLL frequency synthesizer with integrated VCO, covering the upper UHF and lower microwave bands.
Yes, it is specifically a Frequency Synthesizer (RF) type, designed for RF signal generation in wireless and microwave systems.
The CD74HCT7046AE is a different class of part — a through-hole PLL for low-frequency (38 MHz) CMOS logic, not an RF synthesizer. It is not a functional alternative. For a true RF PLL/VCO replacement, look at other LMX2541 variants or the LMX2581 family from TI.
