That temperature band suits under-hood and cabin-mounted ECUs, ADAS sensor modules, and infotainment head units where a quartz oscillator might drift or fail under vibration. The supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without a separate LDO — one less component in the power tree. Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. Maximum supply current is 35mA when enabled and 22mA when disabled — the disable current is still present because the internal MEMS and PLL remain biased, so a hard power switch saves more power if the clock is off for long periods.","metaTitle":"DSC1121AI2-010.0000T MEMS Oscillator 10 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121AI2-010.0000T MEMS XO, 10 MHz, CMOS output, ±25ppm stability, AEC-Q100, -40°C to 85°C, 6-SMD.
