The Enable/Disable function lets the system shut down the oscillator when the clock is not needed, reducing supply current from 35 mA max to 22 mA max in the disabled state. ## MEMS vs quartz – sourcing and reliability angle The base resonator is MEMS rather than quartz, which typically offers better resistance to shock and vibration and shorter manufacturing lead times — a practical advantage when quartz supply tightens. Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, it fits standard oscillator footprints and is compatible with reflow soldering. Supplied in Tape & Reel (TR) for automated pick-and-place assembly.","metaTitle":"DSC1121CE1-133.3333T MEMS XO – 133.3333 MHz CMOS, Active","metaDescription":"Microchip DSC1121CE1-133.3333T – 133.3333 MHz MEMS oscillator, CMOS output, ±50 ppm, 2.25V–3.6V, -20°C to 70°C, 6-SMD.
