The MEMS resonator eliminates the quartz-crystal start-up time and vibration sensitivity trade-offs, so the oscillator is ready within microseconds of power-up and holds frequency through moderate mechanical shock. ## Supply voltage range and power budget Operates from 2.25 V to 3.6 V — the wide supply tolerance lets it share a 3.3 V or 2.5 V rail without a dedicated LDO, simplifying the power tree. Housed in a 3.20 mm x 2.50 mm 6-SMD no-lead package (0.90 mm seated height) — the compact footprint fits dense PCB layouts, but the no-lead terminations require a solder-paste stencil with a 0.20 mm aperture for reliable fillet formation.","metaTitle":"DSC1122CI1-156.2500TA – 156.25 MHz LVPECL MEMS Oscillator","metaDescription":"Active MEMS XO, 156.25 MHz LVPECL output, ±50 ppm stability, -40°C to 85°C industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"LVPECL","Series":"DSC1122","Package":"Tape & Reel (TR); Cut Tape (CT)","Ratings":"-","Function":"Enable/Disable","Frequency":"156.25 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1122","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"58mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9eb455e34e1b4ad4aed847bfc84d48fa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1122CI1-156.2500TA RoHS compliant?","answer":"The part is listed as RoHS compliant per Microchip's standard material declaration for the DSC1122 series — confirm the specific date-code compliance with your distributor at RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122CI1-156.2500TA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122CI1-156.2500TA when reusing this data.
