The 2.25V to 3.6V supply range means it can be powered directly from a 2.5V, 3.0V, or 3.3V rail without an intermediate LDO, simplifying the power tree and reducing BOM count. ## Enable/Disable function and supply current budgeting The Enable/Disable pin allows the output to be tri-stated while the oscillator remains powered, dropping the supply current from 35 mA (max) to 22 mA (max) — useful for power-sensitive designs that gate the clock to a peripheral without cycling the oscillator's own supply. ## Active lifecycle — no design-in risk It is a current production part suitable for new designs and volume builds. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1121CI2-020.0000 – Microchip MEMS XO, 20 MHz, CMOS","metaDescription":"Microchip DSC1121CI2-020.0000 – 20 MHz MEMS XO, CMOS output, ±25 ppm stability, 2.25V–3.6V supply, -40°C to 85°C.
