Because the base resonator is silicon MEMS rather than a quartz crystal, the part is inherently more shock- and vibration-tolerant than a quartz oscillator — relevant for industrial or portable equipment where mechanical stress is a concern. ## Package, footprint, and enable/disable function Housed in a 6-SMD no-lead package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm — a standard 3.2×2.5 mm oscillator footprint that matches many quartz oscillator pads, easing drop-in replacement. The enable/disable function (pin 1) lets the system hold the output in high-impedance state, useful for power sequencing or shared-clock buses where the oscillator must be tri-stated during test.","metaTitle":"DSC1121CL1-027.0000T MEMS XO 27 MHz CMOS - Microchip","metaDescription":"Active DSC1121CL1-027.0000T MEMS oscillator, 27 MHz, CMOS output, ±50ppm stability, 2.25-3.6V supply, -40 to 105°C.
