No internal PLL means this is a clean distribution and signal-conditioning part, not a synthesizer; the output edges track the input jitter without adding phase-noise multiplication from a loop filter. ## Supply rail tolerance — 3.3 V only, no margin games The supply range is 3.15 V to 3.45 V — a tight window centred on 3.3 V. A 3.0 V rail or a 3.6 V rail is outside the operating envelope. If your board runs a 3.3 V bus with ±5 % regulation, you are inside the window; a 3.3 V rail that droops to 3.1 V under load still meets the lower bound. Plan the local decoupling accordingly — the 48-WFQFN exposed pad needs a solid ground-plane return for the high-speed outputs.","metaTitle":"LMK03000CISQX/NOPB Clock Conditioner, 1.296 GHz, 1:8 Fanout","metaDescription":"TI LMK03000CISQX/NOPB clock conditioner, 1.296 GHz max, 1:8 LVDS/LVPECL fanout, 3.15-3.45 V supply, 48-WQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","PLL":"No","Type":"Clock Conditioner","Input":"LVCMOS, LVDS, LVPECL","Output":"LVDS, LVPECL","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"1.296GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Base Product Number":"LMK03000","Ratio - Input:Output":"1:8","Operating Temperature":"-40°C~85°C","Supplier Device Package":"48-WQFN (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.5875","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Does LMK03000CISQX/NOPB support LVDS output?","answer":"Yes, the outputs are LVDS or LVPECL, selectable per the device configuration. The input accepts LVCMOS, LVDS, or LVPECL, so the part can translate between signal standards as well as fan out."},{"question":"Is LMK03000CISQX/NOPB compatible with 3.3 V systems?","answer":"Yes, the supply range is 3.15 V to 3.45 V, centred on 3.3 V.

If your application needs to multiply or clean a noisy reference clock, the LMK04000 is the relevant family; if you need low-additive-jitter distribution of an already-clean clock, the LMK03000 fits."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMK03000CISQX-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LMK03000CISQX-NOPB when reusing this data.
