That replaces four discrete quartz oscillators and their associated bypass caps, freeing board area on a dense clock tree. ## Supply flexibility and output control Supply voltage spans 2.25 V to 3.6 V — the same BOM position works on a 2.5 V or 3.3 V rail without a separate regulator. ## Active lifecycle, tape-and-reel delivery Product status is Active — no EOL notice, no last-time-buy window. Store the reels dry: the 20-VFQFN exposed pad is moisture-sensitive, and the reel label carries the MSL level.","metaTitle":"DSC400-2222Q0105KI1T MEMS XO – 4 LVPECL Outputs, Active","metaDescription":"Microchip DSC400-2222Q0105KI1T XO (Standard) MEMS oscillator.

The MEMS resonator is more shock-tolerant than quartz. The pinout and footprint of the 20-VFQFN package differ from a standard 7×5 mm or 5×3.2 mm quartz oscillator; confirm the PCB land pattern against the datasheet before committing."},{"question":"Is DSC400-2222Q0105KI1T compatible with a 2.5 V supply?","answer":"Yes.
