The MEMS base resonator replaces a quartz crystal, giving better shock and vibration immunity — relevant for engine-bay or chassis-mounted ECUs that see 50 g mechanical shock during assembly or operation. ## Supply voltage and enable/disable for power-conscious designs The enable/disable pin lets the system shut down the oscillator output, dropping supply current from 35 mA to 22 mA — useful in sleep-mode power budgets where every milliampere counts. ## Active lifecycle — order against your BOM Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1121CI2-051.8400 Microchip MEMS XO 51.84 MHz CMOS","metaDescription":"Microchip DSC1121CI2-051.8400 — 51.84 MHz MEMS XO, CMOS output, ±25 ppm stability, AEC-Q100 qualified, -40°C to 85°C.
