Operates from 2.25 V to 3.6 V — the wide margin means the same BOM entry works on a 2.5 V FPGA bank and a 3.3 V PHY rail without a separate regulator. Rated for -40°C to 85°C with ±50 ppm frequency stability; that stability band covers the full temperature range, so the 156.25 MHz output stays inside the Ethernet MAC's ppm budget across the industrial ambient. ## Enable/Disable and package fit The 5.00 mm x 3.20 mm body with 0.90 mm height fits standard 20-VFQFN land patterns; the exposed pad requires a thermal via array under the package to pull heat into the ground plane, not a separate heatsink.","metaTitle":"DSC400-2222Q0104KI1 MEMS XO, LVPECL, 125/100/200/156.25 MHz","metaDescription":"Microchip DSC400-2222Q0104KI1: quad-output LVPECL XO, ±50 ppm stability, -40 to 85°C, 2.25-3.6 V supply.
