For a 100 MHz clock, ±25 ppm equals ±2.5 kHz of absolute frequency error. This keeps the clock within the capture range of most Ethernet PHYs, USB controllers, and FPGA PLLs without needing a separate VCXO. The industrial temperature grade means the oscillator holds its spec in outdoor telecom cabinets, factory-floor PLCs, and engine-bay ECUs where ambient can hit 85°C. ## Active production with wide supply tolerance The supply voltage range of 2.25 V to 3.6 V covers both 2.5 V and 3.3 V rails without a separate LDO, simplifying the power tree. ## 20-QFN footprint and tape-and-reel packaging Packaged in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm body, 0.90 mm height). Store the reels in a dry cabinet if the MSL rating requires it; the QFN's exposed pad is moisture-sensitive.","metaTitle":"DSC400-1111Q0001KI2T MEMS XO – 100 MHz, ±25 ppm, -40 to 85°C","metaDescription":"DSC400-1111Q0001KI2T – Microchip MEMS XO, 4-output 100 MHz LVCMOS, ±25 ppm stability, 2.25-3.6 V, -40 to 85°C, 20-QFN.
