Outputs are configurable as LVCMOS or LVDS, letting the same part drive both a high-speed SerDes reference and a lower-frequency system clock without a separate fanout buffer. The 2.25 V to 3.6 V supply range covers 2.5 V and 3.3 V logic rails without an external regulator — a single rail powers the entire clock tree. ## Package footprint and board-level notes Housed in a 20-VFQFN with exposed pad, the 5.00 mm x 3.20 mm body has a 0.90 mm seated height — low enough for mezzanine card spacing in 1U rack equipment. Supplied on Tape & Reel (TR), consistent with automated pick-and-place for medium-to-high volume builds. No minimum order quantity is assumed — quoted per your line item.","metaTitle":"DSC400-3111Q0088KI2T MEMS XO Oscillator – Microchip","metaDescription":"Active MEMS XO oscillator from Microchip. 4 outputs: 148.25 MHz, 12/24 MHz, 25/100 MHz.
