The MEMS base resonator eliminates quartz crystal startup delays and is inherently more shock-tolerant — relevant for portable instrumentation or equipment that sees vibration during transport. ## ±25 ppm stability across industrial temperature range At 100 MHz, that is a maximum frequency error of ±2.5 kHz — tight enough for most PCIe reference clock and Ethernet PHY applications without an external VCXO or PLL. The supply voltage spans 2.25 V to 3.6 V, so the oscillator can run from a 2.5 V or 3.3 V rail without an intermediate regulator — one less component in the power tree.","metaTitle":"DSC400-1444Q0060KI2 MEMS XO – 100 MHz ×3 + 25 MHz","metaDescription":"Microchip DSC400-1444Q0060KI2: MEMS XO, 100 MHz (×3) + 25 MHz outputs, HCSL/LVCMOS, ±25 ppm, -40 to +85 °C, 20-VFQFN.
