The MEMS base gives it better resistance to shock and vibration — useful in engine-bay or chassis-mounted ECUs where a quartz can fail from mechanical stress. Output is CMOS, so it drives standard digital logic inputs directly without a level translator. The Enable/Disable function lets the system shut off the oscillator for low-power sleep modes — the disable current drops to 22 mA max from 35 mA max active. ## AEC-Q100 qualification and temperature grade That covers under-hood and cabin domains where the ambient temperature can hit 85°C on a hot day with solar load. The ±50 ppm frequency stability holds the clock accuracy needed for CAN, LIN, or Ethernet PHY reference clocks. ## Supply voltage flexibility and package footprint Supply range is 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without an extra regulator. The 6-SMD no-lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — fits tight PCB stacks in automotive sensor modules or handheld test gear.","metaTitle":"DSC1121DI1-125.0000 – 125 MHz MEMS XO, CMOS, AEC-Q100","metaDescription":"DSC1121DI1-125.0000: 125 MHz XO (Standard), CMOS output, AEC-Q100, -40°C to +85°C, 2.25V–3.6V supply.
