The 42 mA max supply current supports the 0.9V peak-to-peak swing into a 50-Ω differential termination without an external level shifter. ## Industrial temperature range for outdoor and engine-bay use The MEMS resonator survives the 50 g shock and 10–2000 Hz vibration profile typical of these environments — a quartz crystal would require a separate shock mount. ## Wide supply voltage and standby power-down The 2.25V to 3.6V supply range covers both 2.5V and 3.3V logic rails without a dedicated regulator — a single BOM line works across two voltage domains.","metaTitle":"DSC1104CI1-027.0000 27 MHz HCSL MEMS Oscillator – Active","metaDescription":"Microchip DSC1104CI1-027.0000: XO (Standard) MEMS oscillator, 27 MHz, HCSL output, 2.25-3.6V supply, -40 to +85°C.
