No leads to bend or break — the part sits flat and reflows cleanly with a standard hot-air profile. ## Supply rail flexibility and power budget The 2.25V to 3.6V supply range lets this oscillator run directly off a 2.5V or 3.3V rail without an intermediate LDO. The DSC1122 series remains a current design-in candidate. No pin-compatible second source is documented, but the 3.2x2.5 mm LVPECL oscillator market has several functional equivalents — confirm the Enable/Disable logic polarity and supply voltage tolerance before substituting.","metaTitle":"DSC1122CI1-125.0000T 125 MHz LVPECL MEMS Oscillator -","metaDescription":"Active XO (Standard) MEMS oscillator, 125 MHz LVPECL output, 2.25-3.6V, -40°C to 85°C, 6-SMD no-lead.","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)","Ratings":"-","Function":"Enable/Disable","Frequency":"125 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 the DSC1122CI1-125.0000T a good replacement for a standard quartz oscillator?","answer":"Yes, in most applications. The MEMS resonator provides faster start-up and better long-term aging than quartz, with the same ±50 ppm stability. The 6-SMD footprint is a drop-in match for many 3.2x2.5 mm quartz oscillators, but verify the Enable/Disable pin function and supply voltage range match your existing BOM."},{"question":"What is the footprint of the DSC1122CI1-125.0000T?","answer":"The package is 3.20mm x 2.50mm with a 0.90mm seated height — a standard 6-SMD no-lead oscillator footprint. The land pattern matches the common 3.2x2.5 mm oscillator layout used across the industry."},{"question":"How does the DSC1122CI1-125.0000T compare to other 125 MHz LVPECL oscillators?","answer":"The key differentiator is the MEMS resonator: faster start-up, better shock and vibration tolerance, and no quartz aging drift. The 2.25V to 3.6V supply range is wider than many fixed-voltage LVPECL oscillators, which often require a 3.3V rail only. The ±50 ppm stability is standard for this class."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122CI1-125.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122CI1-125.0000T when reusing this data.
