It accepts up to three input sources — CML, HCSL, HSTL, LVDS, LVPECL, SSTL, or a crystal — and distributes the selected clock to five outputs in HCSL, LVCMOS, LVDS, or LVPECL format. The 3.1 GHz maximum frequency covers PCIe Gen4/5 reference clocks, 100G Ethernet, and high-speed ADC/DAC sampling clocks. At this speed, the differential input-to-output path (Yes/Yes per the spec) preserves signal integrity without external level shifting. The part operates from a 3.15V to 3.45V supply — a narrow rail typical of high-performance clocking ICs that need tight PLL/VCO noise margins. ## Active lifecycle — no end-of-life risk Because it is an active TI catalog part, it is sourced through authorized distribution channels.","metaTitle":"TI LMK00304SQE/NOPB Fanout Buffer, 3.1 GHz, 32-WQFN","metaDescription":"Texas Instruments LMK00304SQE/NOPB fanout buffer/mux/translator, 3.1 GHz max, 3:5 I/O, CML/HCSL/LVDS/LVPECL in, HCSL/LVCMOS/LVDS/LVPECL out, 32-WQFN, active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","Type":"Fanout Buffer (Distribution), Multiplexer, Translator","Input":"CML, HCSL, HSTL, LVDS, LVPECL, SSTL, Crystal","Output":"HCSL, LVCMOS, LVDS, LVPECL","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"32-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"3.1 GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Number of Circuits":"1","Base Product Number":"LMK00304","Ratio - Input:Output":"3:5","Operating Temperature":"-40°C~85°C","Supplier Device Package":"32-WQFN (5x5)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.8200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ccd8bf3fd4ecbc0625e63e0b3318c8f8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK00304SQE%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What input and output formats does the LMK00304SQE/NOPB support?","answer":"The input accepts CML, HCSL, HSTL, LVDS, LVPECL, SSTL, or a crystal.
