Its function is to lock a voltage-controlled oscillator to a reference frequency, producing a clean, programmable output for upconversion or downconversion stages. As a Clock & Timing IC, it sits in the signal chain between the reference crystal and the VCO, typically found in base stations, test equipment, or satellite-communication transceivers where phase noise and lock time matter. ## Active production and sourcing posture A critical compliance note: the LMX2354SLDX is RoHS non-compliant. If your BOM requires RoHS exemption for leaded solder or high-reliability applications, this part fits. For RoHS-mandated assemblies, confirm the exemption or plan for a waiver. ## Package format and board-level fit For automated pick-and-place, verify that your feeder system can handle tube-fed components or plan for manual placement.","metaTitle":"LMX2354SLDX PLL Frequency Synthesizer – Texas Instruments","metaDescription":"Texas Instruments LMX2354SLDX PLL frequency synthesizer, active production, RoHS non-compliant, bulk package.","metaKeywords":null},"attributes":{"series":"*","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Series":"*","Package":"Bulk","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.19","stockQuantity":0,"priceTiers":[{"qty":254,"price":"$1.19000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4842a4b8415144164fde795f3530aff2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source for the LMX2354SLDX?","answer":"The CD74HCT7046AE is a phase-locked loop from the 74HCT series, but it is a different device class: it operates at 38 MHz max, uses through-hole mounting, and runs from a 4.5 V supply.
