That replaces four separate quartz oscillators on the board, saving both layout area and four BOM line items. ## Supply rail flexibility and the enable/disable pin The supply voltage range is 2.25 V to 3.6 V, so a single 2.5 V or 3.3 V rail powers all four outputs. No second regulator needed for mixed-voltage logic families. ## Package footprint and the exposed-pad reality The 20-VFQFN with exposed pad measures 5.00 mm x 3.20 mm and stands 0.90 mm tall. The board layout engineer should plan for that thermal via pattern before the first spin; the footprint alone is not enough.","metaTitle":"DSC400-2222Q0104KE1 MEMS XO – 4 LVPECL Outputs, Active","metaDescription":"DSC400-2222Q0104KE1 from Microchip: MEMS-based XO, 4 LVPECL outputs (125/100/200/156.25 MHz), ±50 ppm stability, 2.25-3.6V supply.

The trade-off is that the MEMS part has a slightly higher phase-noise floor than a high-end quartz OCXO, but for most digital clocking (FPGA reference, Ethernet PHY, switch fabric) the difference is negligible.
