Supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an external regulator — a single BOM line for mixed-voltage designs. ## MEMS resonator — vibration-tolerant alternative to quartz The 6-SMD package with exposed pad (7.00mm x 5.00mm footprint, 0.90mm seated height) matches the industry-standard 7x5 mm oscillator land pattern — a direct board-level swap for quartz oscillators in the same size, provided the supply and output logic (LVPECL) are compatible.","metaTitle":"DSC1122AI1-125.0000 MEMS Oscillator – 125 MHz LVPECL, Active","metaDescription":"Microchip DSC1122AI1-125.0000 XO (Standard), 125 MHz LVPECL output, MEMS resonator, -40°C to 85°C, 2.25V–3.6V supply.","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":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"125 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9eb455e34e1b4ad4aed847bfc84d48fa.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1122AI1-125.0000/alternatives.json"},"ai":{"faq":[{"question":"Is DSC1122AI1-125.0000 a direct drop-in replacement for a quartz oscillator?","answer":"The 7x5 mm 6-SMD package and pinout match the industry-standard quartz oscillator footprint, so the board-level swap is mechanical. The electrical swap depends on your system: the LVPECL output is a differential signal (not single-ended CMOS/TTL), and the supply range (2.25V–3.6V) must match the rail. If your design expects a quartz oscillator with LVPECL output, this MEMS part is a functional replacement with better vibration immunity."},{"question":"Can DSC1122AI1-125.0000 be used in high-vibration environments compared to quartz?","answer":"Yes. The MEMS resonator is a silicon structure with no moving quartz blank — it is inherently more resistant to shock and vibration than a quartz crystal. This makes it a better choice for industrial motor drives, outdoor telecom, and engine-bay applications where quartz oscillators can experience frequency jitter or microphonic effects."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122AI1-125.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122AI1-125.0000 when reusing this data.
