Output format options include CML, HCSL, LVDS, LVPECL, and LVCMOS, covering the common clocking standards for FPGA reference clocks, SERDES, Ethernet PHYs, and high-speed ADC/DAC sampling clocks. The PLL includes a bypass mode, allowing the input reference to pass through cleanly — useful for system test modes or when a low-jitter external clock is preferred over the synthesised output. Supply voltage is 3.15 V to 3.45 V, nominally a 3.3 V rail — the PLL's jitter performance depends on a clean, low-noise supply, so a dedicated LDO or ferrite-bead filter on the 3.3 V plane is standard practice for this class of device. Surface-mount assembly with a standard reflow profile; the exposed pad requires a solder-paste stencil opening that covers 50–80 % of the pad area to avoid voiding. No special bake-out is needed for the moisture-sensitive level (MSL) if the floor life is within limits. ## Active lifecycle and sourcing Standard procurement through authorized distribution applies; no date-code or surplus-channel risk for this part number.","metaTitle":"Texas Instruments LMK03318RHST PLLatinum Clock Generator","metaDescription":"Texas Instruments LMK03318RHST PLLatinum clock generator, 1 GHz max, 2:8 fanout, LVCMOS input, CML/HCSL/LVDS/LVPECL/LVCMOS outputs, 48-WQFN, active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","PLL":"Yes with Bypass","Input":"LVCMOS","Output":"CML, HCSL, LVCMOS, LVDS, LVPECL","Series":"PLLatinum™","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"1GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Divider/Multiplier":"Yes/Yes","Number of Circuits":"1","Base Product Number":"LMK03318","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":"$18.1000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/79619eccbf9a8bfde2fed80375a24c61.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK03318RHST/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LMK03318RHST and get a price?","answer":"We source the LMK03318RHST through independent distribution."},{"question":"What output formats does the LMK03318RHST support?","answer":"It supports CML, HCSL, LVCMOS, LVDS, and LVPECL outputs, covering the common clocking standards for high-speed digital interfaces."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMK03318RHST","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LMK03318RHST when reusing this data.
