The supply range of 2.25 V to 3.6 V covers both 2.5 V and 3.3 V logic rails without an intermediate regulator — a single BOM line serves mixed-voltage domains on the same PCB. Frequency stability is specified at ±25 ppm, tight enough for most 1 GbE and PCIe Gen 1/2 reference clocks without the cost of a TCXO. The MEMS resonator holds this stability across temperature without a compensation loop. ## Package and layout note The 20-VFQFN Exposed Pad package (5.00 mm × 3.20 mm, 0.90 mm height) requires a thermal-via array under the centre pad for heat sinking and mechanical stability.","metaTitle":"DSC400-2222Q0118KI2 MEMS XO – 100/125 MHz LVPECL, Active","metaDescription":"Microchip DSC400-2222Q0118KI2: quad-output LVPECL XO, 100/125 MHz, ±25 ppm stability, 2.25-3.6 V supply, industrial temp.
