The 2:8 input-to-output ratio means you can route a clean reference clock to multiple destinations — ADCs, FPGAs, or SerDes transceivers — without loading the source oscillator. With a maximum frequency of 1.6 GHz, this buffer handles high-speed serial links (Gigabit Ethernet, PCIe Gen 1/2, or 10G backplane clocks) where edge jitter matters more than the absolute frequency. The differential input and output path (yes/yes) preserves signal integrity across the distribution network. ## Supply rails and temperature grade The device operates from a 3.15 V to 3.45 V supply — a tight window that demands a clean rail. A low-noise LDO feeding this buffer is standard practice; the 48-WFQFN exposed pad (7x7 mm) provides a thermal path to the ground plane, which also serves as the return for the high-frequency outputs.","metaTitle":"TI LMK01000ISQX/NOPB Fanout Buffer, 1.6 GHz, LVDS/LVPECL","metaDescription":"Texas Instruments LMK01000ISQX/NOPB fanout buffer (distribution) and divider. 1.6 GHz max, 2:8 differential I/O, LVDS/LVPECL outputs.","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), Divider","Input":"Clock","Output":"LVDS, LVPECL","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"1.6 GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Number of Circuits":"1","Base Product Number":"LMK01000","Ratio - Input:Output":"2:8","Operating Temperature":"-40°C~85°C","Supplier Device Package":"48-WQFN (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.5545","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/815b4a63fa4862ee37c5780011bcfa1f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK01000ISQX%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LMK01000ISQX/NOPB and how do I get a price?","answer":"This part is sourced to order against an RFQ through independent and authorized distribution."},{"question":"What is the input and output type of LMK01000ISQX/NOPB?","answer":"The input is a clock signal (differential), and the outputs are LVDS or LVPECL — both differential families.
