Rated ±25 ppm frequency stability over -20°C to +70°C, the part meets the timing margin for most USB, 10/100 Ethernet, and general-purpose digital interfaces without external compensation. Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails directly — no intermediate regulator needed. ## MEMS resonator vs quartz – reliability angle This matters for deployed equipment in industrial automation, outdoor telecom, or transport where the board sees repeated G-force. The DSC400 series is a current Microchip catalog line; design-in for new builds is straightforward. 20-VFQFN with exposed pad, 5.00 mm x 3.20 mm body, 0.90 mm height. Enable/Disable function on a dedicated pin allows the outputs to be tri-stated for low-power sleep modes without removing supply voltage.","metaTitle":"DSC400-1111Q0091KE2T MEMS XO – 4-output LVCMOS, ±25ppm","metaDescription":"Microchip DSC400-1111Q0091KE2T MEMS XO: 12/24/48/14.25 MHz outputs, LVCMOS, ±25ppm, 2.25-3.6V, 20-VFQFN.
