That frequency ceiling makes it a candidate for cleaning up reference clocks feeding high-speed ADCs, DACs, or SerDes transceivers in base-station, test-and-measurement, or networking gear. The 2:5 input-to-output ratio means you can take one reference and distribute five conditioned copies — useful for fanning a clean clock across multiple converter channels or FPGA banks without adding separate PLLs per lane. The 1.57 GHz maximum frequency sets the upper bound for the output clock rate. If your ADC sample clock or SerDes reference is below that, this part can condition it; if you need 2.5 GHz, you need a different part. Supply voltage is 3.15 V to 3.45 V — a tight 3.3 V rail with ±5 % tolerance. A noisy or droopy 3.3 V supply will degrade the jitter-cleaning performance, so plan for a dedicated LDO feeding this IC. The base product number is LMK04011; the BISQ suffix indicates the industrial temperature range and the 48-WQFN package. The /NOPB suffix confirms lead-free (RoHS) construction.","metaTitle":"LMK04011BISQ/NOPB Clock Conditioner PLL 1.57 GHz - Texas","metaDescription":"Texas Instruments LMK04011BISQ/NOPB clock conditioner with PLL, 1.57 GHz max, LVCMOS/LVDS/LVPECL input, 2VPECL/LVPECL output, industrial temp -40°C to 85°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","PLL":"Yes","Type":"Clock Conditioner","Input":"LVCMOS, LVDS, LVPECL","Output":"2VPECL, LVPECL","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"1.57GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Divider/Multiplier":"Yes/Yes","Number of Circuits":"1","Base Product Number":"LMK04011","Ratio - Input:Output":"2:5","Operating Temperature":"-40°C~85°C","Supplier Device Package":"48-WQFN (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.5600","priceTiers":[{"qty":17,"price":"$18.56000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b7a91d5183ee36f0cc125d1bbe55f0ba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK04011BISQ%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source to LMK04011BISQ/NOPB — CD74HCT7046AE?","answer":"The CD74HCT7046AE is a PLL, but it is a fundamentally different class: it operates at 38 MHz max (vs 1.57 GHz), uses through-hole packaging, and lacks differential I/O.
