At 0.90 mm seated height it fits under a mezzanine card or in a tight enclosure stack.","metaTitle":"DSC400-3333Q0078KE2 MEMS XO, 4×125 MHz LVDS, Active","metaDescription":"Microchip DSC400-3333Q0078KE2: Active MEMS XO, 4 outputs at 125 MHz LVDS, ±25 ppm stability, -20 to 70°C, 20-VFQFN.

We source it through independent distribution and quote to order against your BOM quantity. Availability and current pricing are confirmed at RFQ — no stock-holding claim is made here."},{"question":"What is the output type and frequency stability of the DSC400-3333Q0078KE2?","answer":"Output is LVDS. Frequency stability is ±25 ppm across the -20 to 70°C operating range."},{"question":"Is the DSC400-3333Q0078KE2 compatible with a 3.3 V supply?","answer":"Yes. The supply voltage range is 2.25 V to 3.6 V, so a 3.3 V rail is within spec. The LVDS output common-mode voltage tracks the supply, so the receiver must accept the corresponding input range."},{"question":"Can the DSC400-3333Q0078KE2 replace a quartz oscillator?","answer":"Functionally yes — it provides four 125 MHz LVDS clocks from one package instead of four quartz cans. The MEMS resonator is more shock and vibration tolerant than a quartz crystal, but the 20-VFQFN footprint is different from a standard 7×5 mm oscillator, so the PCB layout must change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-3333Q0078KE2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-3333Q0078KE2 when reusing this data.
