Operating from 2.25 V to 3.6 V, the part covers 2.5 V and 3.3 V logic rails without an external regulator — the wide input tolerance absorbs rail droop from a switching converter. ## Package and layout — 20-VFQFN with exposed pad Housed in a 20-VFQFN with an exposed thermal pad, the 5.00 mm x 3.20 mm footprint matches standard oscillator land patterns — the pad must be soldered to a ground plane with thermal vias to keep the junction temperature within the commercial range.","metaTitle":"DSC400-1111Q0034KE1 MEMS XO – Quad 50 MHz LVCMOS, Active","metaDescription":"Microchip DSC400-1111Q0034KE1: MEMS-based XO, four 50 MHz LVCMOS outputs, ±50 ppm, -20 to 70°C, 20-VFQFN.
