That means one component replaces up to four discrete oscillators, freeing board space and reducing BOM count on high-speed digital designs. The supply range spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without an extra regulator — useful when the board already has those rails and you want to avoid a second LDO just for the clock. ## Package footprint and board layout considerations The 5.00mm x 3.20mm body with 0.90mm height (0.197\" x 0.126\" x 0.035\") and exposed thermal pad demands a via-in-pad or thermal-via array under the centre pad for proper heat sinking — a standard 4-layer board with a ground-plane flood under the part handles it cleanly. ## Active lifecycle — no design-in deadline Product status is Active per Microchip's current lifecycle designation.","metaTitle":"DSC400-2222Q0022KI2 MEMS Oscillator – 125/100 MHz LVPECL","metaDescription":"Microchip DSC400-2222Q0022KI2 XO (Standard) MEMS oscillator, 4 outputs (125, 100, 100, 125 MHz), LVPECL, ±25 ppm, -40 to 85°C, 20-VFQFN.
