The 2.25V to 3.6V supply rail tolerance means it can run from a 2.5V or 3.3V rail without an intermediate regulator — one less component on the BOM. ## AEC-Q100 qualification and deployment context This qualifies it for under-hood or chassis-domain ECUs where the ambient temperature can reach 85°C and the board sees vibration from the engine or road surface. ## Enable/Disable function and power budgeting With the output disabled, the supply current drops from 35 mA typical to 22 mA maximum — a useful power save in battery-backed or thermal-constrained designs where the clock tree can be gated during sleep modes.","metaTitle":"DSC1121NI1-133.3300 MEMS Oscillator 133.33 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121NI1-133.3300 XO (Standard) MEMS oscillator, 133.33 MHz CMOS output, ±50 ppm stability, -40°C to +85°C, AEC-Q100.
