The MEMS resonator eliminates the quartz crystal's startup time and vibration sensitivity — a direct swap for a standard 26 MHz crystal oscillator on the same PCB footprint, with the added benefit of a wider supply range (2.25V to 3.6V) that covers 2.5V and 3.3V logic rails without a separate regulator. ## Automotive-grade reliability and temperature range For battery-powered or thermal-constrained designs, that 13 mA saving per oscillator adds up across multiple clock domains. Microchip lists the DSC1121BI1-026.0000 as Active.","metaTitle":"DSC1121BI1-026.0000 MEMS XO 26MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121BI1-026.0000 XO (Standard) 26MHz CMOS output, MEMS resonator, 2.25V-3.6V supply, AEC-Q100, -40°C~85°C, 6-SMD.
