It handles up to 3.1 GHz on the input, which means it can distribute a 10G Ethernet reference clock or a high-speed ADC sample clock without needing a separate prescaler. Input flexibility covers LVCMOS, LVDS, LVPECL, and RF sinewave — the same part can buffer a crystal oscillator output or a differential PLL clock. The output side mirrors the input types, so the signal level stays compatible with the downstream load. ## Supply and temperature guardrails A 3.3 V rail with ±5 % tolerance keeps the part inside the window, but a 3.3 V rail with ±10 % tolerance drifts to 3.63 V at the high end — that is out of spec. The power tree needs a regulated LDO or a clean DC-DC output.","metaTitle":"LMK01801BISQE/NOPB Clock Buffer 3.1 GHz 48-WQFN - Texas","metaDescription":"Texas Instruments LMK01801BISQE/NOPB active clock fanout buffer/divider/mux. 3.1 GHz max, 1:8/1:6 ratio, LVCMOS/LVDS/LVPECL I/O, industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","Type":"Fanout Buffer (Distribution), Divider, Multiplexer","Input":"LVCMOS, LVDS, LVPECL, RF Sinewave","Output":"LVCMOS, LVDS, LVPECL","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"3.1 GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Number of Circuits":"2","Base Product Number":"LMK01801","Ratio - Input:Output":"1:8, 1:6","Operating Temperature":"-40°C~85°C","Supplier Device Package":"48-WQFN (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.6800","priceTiers":[{"qty":1,"price":"$16.68000","currency":"USD"},{"qty":10,"price":"$15.32500","currency":"USD"},{"qty":25,"price":"$14.69040","currency":"USD"},{"qty":100,"price":"$12.94330","currency":"USD"},{"qty":250,"price":"$12.30804","currency":"USD"},{"qty":500,"price":"$11.51396","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/348483418dc3b9657b724fb515be1ca6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK01801BISQE%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum frequency of LMK01801BISQE/NOPB?","answer":"3.1 GHz.
