This frequency is a standard line-rate reference for 10 GbE, SONET OC-192, and FPGA transceiver reference clocks. ## Supply rail and thermal budget in the 6-QFM package The 162 mA supply current at 3.3 V nominal means the oscillator dissipates roughly 0.53 W. In the 6-QFM (7x5) package without a dedicated thermal pad, that heat exits through the module's solder joints and the board copper. The 3.135V to 3.465V supply window is tight enough that a 3.3 V rail with ±5% tolerance covers it; a 2.5 V rail does not.","metaTitle":"LMK61E2-156M25SIAR Clock Oscillator, 156.25 MHz","metaDescription":"TI LMK61E2-156M25SIAR clock oscillator, 156.25 MHz fixed output, 3.135V~3.465V supply, 162 mA, -40°C~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)","Frequency":"156.25MHz","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":"LMK61E2","Operating Temperature":"-40°C~85°C","Supplier Device Package":"6-QFM (7x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.6950","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4f79d073177f07fede4fe798bc432227.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK61E2-156M25SIAR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMK61E2-156M25SIAR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LMK61E2-156M25SIAR when reusing this data.
