Supply voltage range of 2.25 V to 3.6 V covers common 2.5 V and 3.3 V rails; no separate regulator needed if the rail is within that window. Housed in a 20-VFQFN with exposed pad, 5.0 mm x 3.2 mm body, 0.90 mm height — the pad must be soldered to a ground plane for proper thermal and electrical performance. Supplied in Tape & Reel (TR) — compatible with standard pick-and-place and reflow profiles for the VFQFN package.","metaTitle":"DSC400-4334Q0022KI2T MEMS XO – HCSL/LVDS Quad Output, Active","metaDescription":"Microchip DSC400-4334Q0022KI2T: MEMS-based XO, 4 outputs (2x125MHz + 2x100MHz), HCSL/LVDS, ±25ppm, -40~85°C, 20-VFQFN.
