The 6-SMD, No Lead package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard footprint that matches many quartz oscillator pads, so a board designed for a 5x3.2 mm can often take this MEMS part without a layout change.","metaTitle":"DSC1122BI1-125.0000 MEMS XO 125 MHz LVPECL Active","metaDescription":"Microchip DSC1122BI1-125.0000 XO (Standard) MEMS oscillator, 125 MHz LVPECL output, ±50ppm stability, -40°C to 85°C, 6-SMD.

The 125 MHz frequency is common for Ethernet PHY reference clocks and data-converter sampling clocks."},{"question":"Is the DSC1122BI1-125.0000 obsolete or active?","answer":"Active. Microchip lists it as current production — no end-of-life or last-time-buy window. You can design it into new builds and replenish existing BOM lines without a forced migration."},{"question":"Can I use DSC1122BI1-125.0000 with a 2.5V supply?","answer":"Yes. The supply range is 2.25V to 3.6V, so a 2.5V rail is well within spec. No external regulator needed — just connect the rail and the Enable pin to Vdd if you want the oscillator running continuously."},{"question":"What is the footprint of DSC1122BI1-125.0000?","answer":"6-SMD, No Lead, 5.00 mm x 3.20 mm body, 0.90 mm seated height. This matches the common 5x3.2 mm oscillator footprint used by many quartz and MEMS XOs — a board laid out for that size can usually accept this part without a layout revision."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122BI1-125.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122BI1-125.0000 when reusing this data.
