The supply voltage range of 2.25 V to 3.6 V covers common 2.5 V and 3.3 V rails without an external regulator — one less component on the BOM. Frequency stability is ±50 ppm, a typical budget for 100BASE-T Ethernet and general-purpose processor clocking where the total timing error must stay under 100 ppm. Housed in a 20-VFQFN with exposed pad, the 5.00 mm x 3.20 mm body and 0.90 mm height suit dense PCB layouts where height clearance is tight — think mezzanine cards or blade servers. The exposed thermal pad requires a via-in-pad or a solid ground-plane connection for heat sinking; the datasheet's recommended footprint should be followed to keep junction temperature within limits.","metaTitle":"DSC400-1111Q0085KI1T MEMS XO – 25 MHz & 125 MHz LVCMOS","metaDescription":"Microchip DSC400-1111Q0085KI1T: MEMS XO (Standard), dual LVCMOS outputs 25 MHz & 125 MHz, ±50 ppm stability, -40°C to 85°C, 20-VFQFN.
