The MEMS die is inherently more resistant to shock and vibration than a quartz blank, which matters for equipment that ships assembled or sees mechanical stress in the field. ## Industrial temperature and supply flexibility The supply range spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails directly — no extra regulator or level shifter for the oscillator core. ## Enable/Disable function and package footprint An Enable/Disable pin lets the system gate the outputs for power saving or test modes without removing supply. The 20-VFQFN with exposed pad (5.00 mm × 3.20 mm body, 0.90 mm max height) requires a thermal via pattern under the pad for proper heat transfer — the datasheet layout recommendation should be followed to keep junction temperature within limits. ## Active lifecycle — design-in ready This part is suitable for new designs and production builds.","metaTitle":"DSC400-1111Q0034KI1 MEMS XO – 4×50 MHz LVCMOS","metaDescription":"Microchip DSC400-1111Q0034KI1: MEMS-based XO, 4 outputs at 50 MHz each, LVCMOS, ±50 ppm stability, -40 to +85°C, 20-VFQFN.
