LVPECL logic levels require a DC termination to VCC – 2V, typically via a Thevenin-equivalent resistor pair to the supply and ground; the 151 MHz edge rate also demands controlled-impedance traces on the receiver side. Housed in a 6-SMD no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, the footprint matches industry-standard 3.2×2.5 mm XO pads—a drop-in for existing layouts that expect that outline. ## Active lifecycle—no last-time-buy pressure This is useful in power-sensitive designs where the oscillator can be gated during sleep modes without an external load switch.","metaTitle":"DSC1122CI2-151.0000 – Microchip 151 MHz LVPECL MEMS XO","metaDescription":"Active MEMS oscillator, 151 MHz LVPECL output, ±25 ppm stability, -40°C to 85°C, 6-SMD package.

The DSC1122CI2-151.0000 is specified at ±25 ppm stability and -40°C to 85°C. The CI1 variant typically offers a different stability or temperature grade; consult the DSC1122 ordering guide for the exact mapping."},{"question":"Can I replace a quartz oscillator with this MEMS oscillator on my board?","answer":"Yes, if the board footprint is 3.2mm x 2.5mm 6-SMD no-lead and the supply voltage is within 2.25V to 3.6V. The MEMS version offers faster startup and better shock tolerance, but the output logic must be LVPECL—if your quartz oscillator uses LVCMOS or LVDS, the receiver termination and voltage levels will differ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122CI2-151.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122CI2-151.0000 when reusing this data.
