An OEM auditor will accept this for infotainment, ADAS sensor preprocessing, or body-control modules; for 125°C under-hood locations you need a grade-1 rated oscillator. ## 20 MHz CMOS output and supply flexibility 20 MHz CMOS output directly drives the clock input of an MCU, FPGA, or Ethernet PHY without a level translator. The supply range of 2.25V to 3.6V covers 2.5V and 3.3V rails — a single BOM line works across both voltage domains, which simplifies the power tree in a multi-rail design. Maximum supply current is 35 mA; with the disable function the standby current drops to 22 mA. The enable/disable pin lets a system controller gate the clock to save power in sleep modes, though 22 mA is higher than a typical 32 kHz RTC oscillator — budget accordingly for low-power states. ## MEMS resonator in a 6-SMD no-lead package Base resonator is MEMS, not quartz — the part is inherently shock and vibration tolerant compared to a crystal oscillator. The 6-SMD no-lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The small footprint frees board area, but the no-lead land pattern requires a solder-paste stencil aperture matched to the pad layout — a standard QFN-style footprint works. ## Active production — no EOL pressure Product status is Active. No last-time-buy window, no NRND flag. The DSC1121 series is in volume production from Microchip, so new designs can commit to this order code without a near-term EOL risk. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1121DI1-020.0000T MEMS Oscillator","metaDescription":"Microchip DSC1121DI1-020.0000T MEMS oscillator, 20 MHz CMOS output, AEC-Q100 qualified, ±50 ppm stability, -40°C to 85°C.
