It operates from a 3.135 V to 3.465 V supply rail and draws 162 mA typical. ## Supply and temperature envelope for system timing The 3.135 V to 3.465 V supply range covers both 3.3 V nominal rails with margin for ripple and dropout — a common requirement when the oscillator shares a rail with FPGAs or ASICs that pull the supply down during logic transitions. With a 162 mA supply current at 155.52 MHz, the oscillator's power dissipation is roughly 0.53 W at 3.3 V. The base product number is LMK61, which covers the family of fixed-frequency oscillators in the 6-QFM footprint.","metaTitle":"Texas Instruments LMK61E0-155M52SIAT Clock Oscillator","metaDescription":"Texas Instruments LMK61E0-155M52SIAT clock oscillator, 155.52MHz fixed output, 3.135V-3.465V supply, 162mA, -40°C to +85°C, 6-QFM package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","Type":"Clock Oscillator","Count":"-","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Frequency":"155.52MHz","Mounting Type":"Surface Mount","Package / Case":"6-SMD Module","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Supply":"162 mA","Voltage - Supply":"3.135V ~ 3.465V","Base Product Number":"LMK61","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"6-QFM (7x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.0971","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4f79d073177f07fede4fe798bc432227.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK61E0-155M52SIAT/alternatives.json"},"ai":{"faq":[{"question":"What is the output frequency and supply voltage for the LMK61E0-155M52SIAT?","answer":"The oscillator outputs a fixed 155.52 MHz and operates from a 3.135 V to 3.465 V supply, drawing 162 mA typical."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMK61E0-155M52SIAT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LMK61E0-155M52SIAT when reusing this data.
