The MEMS resonator eliminates the quartz crystal's start-up and aging drift, and the enable/disable function lets you gate the outputs without removing power. ## Supply range and temperature grade Operates from 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V logic rails without an intermediate regulator. The commercial temperature range of -20°C to 70°C fits indoor equipment, office peripherals, and telecom line cards — but not engine-bay or outdoor pole-mount enclosures. ## Package and layout note Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height). The exposed thermal pad must be soldered to a ground-plane island on the PCB for heat sinking; the 0.50 mm pitch QFN demands a solder-paste stencil aperture matched to the datasheet footprint recommendation to avoid bridging. ## Lifecycle and supply posture The part is available for new designs and ongoing production. Sourced and quoted to order against your BOM quantity; current pricing and lead time confirmed at RFQ.","metaTitle":"DSC400-1111Q0111KE1T MEMS XO – Microchip, 4-output LVCMOS","metaDescription":"Microchip DSC400-1111Q0111KE1T MEMS XO: 25/20/24 MHz LVCMOS outputs, 2.25-3.6 V supply, ±50 ppm stability, enable/disable, 20-QFN.
