The 2:5 input-to-output ratio with differential I/O on both sides means one clean reference can fan out to five destinations without external distribution buffers — saving board space and reducing additive phase noise from separate fanout ICs. Input flexibility across LVCMOS, LVDS, and LVPECL lets the conditioner accept whatever clock source the system already carries — a crystal oscillator, another PLL output, or a backplane-distributed reference. Outputs are 2VPECL and LVPECL, the dominant logic family for driving long PCB traces to remote ADCs or FPGAs at GHz rates. Operates from a 3.15 V to 3.45 V supply — the standard 3.3 V rail with 150 mV of headroom on each side. Packaged in a 48-WFQFN with exposed pad, supplier device package 48-WQFN 7x7 mm. ## Sourcing — sealed reels with consistent date codes Supplied in Tape & Reel — the standard carrier for pick-and-place assembly. As an active TI part, inventory moves through authorized distribution and surplus channels. Sealed reels with consistent date codes are the norm; mixed-date auction lots that smell like repackaged returns are the exception to flag at RFQ.","metaTitle":"LMK04011BISQX/NOPB Clock Conditioner, 1.57GHz, Active","metaDescription":"Texas Instruments LMK04011BISQX/NOPB clock conditioner with integrated PLL, 1.57GHz max frequency, LVCMOS/LVDS/LVPECL inputs, 2VPECL/LVPECL outputs, 48-WFQFN.","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":"$15.8010","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2739492f39a7ccf814dd60aec1ed6a91.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK04011BISQX%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What does the 1.57 GHz max frequency mean for my clock tree?","answer":"The 1.57 GHz ceiling covers the sample clock range for most high-speed ADCs (up to 1.5 GSPS) and the reference clock range for 10/25/40 GbE SerDes.
