The 2:8 input-to-output ratio means two reference inputs feed eight programmable outputs, each independently configurable as CML, HCSL, LVCMOS, LVDS, or LVPECL without external level shifters. Differential signalling on both input and output sides preserves signal integrity over board traces to multiple endpoints — a single device can fan out a clean 156.25 MHz to eight SERDES PHYs. Surface-mount assembly; the 0.5 mm pitch QFN demands a solder paste stencil with appropriate aperture ratio to avoid bridging on the centre pad.","metaTitle":"TI LMK05318RGZT Clock IC, 800 MHz, 2:8, 48-VQFN","metaDescription":"Texas Instruments LMK05318RGZT clock generator IC with PLL bypass, 800 MHz max, 2:8 I/O, 1.71V-3.465V, -40°C to 85°C, 48-VQFN.","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","Type":"-","Input":"Clock, LVCMOS","Output":"CML, HCSL, LVCMOS, LVDS, LVPECL","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"48-VFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"800MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"1.71V ~ 3.465V","Divider/Multiplier":"Yes/Yes","Number of Circuits":"2","Base Product Number":"LMK05318","Ratio - Input:Output":"2:8","Operating Temperature":"-40°C~85°C","Supplier Device Package":"48-VQFN (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$21.5000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/875da0f1e6935185204304040719479e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK05318RGZT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMK05318RGZT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LMK05318RGZT when reusing this data.
