The MEMS resonator replaces a quartz crystal, offering better shock and vibration tolerance and faster start-up than a traditional crystal oscillator—relevant for engine control units, ADAS sensors, or infotainment modules that see mechanical stress. Supply voltage spans 2.25V to 3.6V, covering 3.3V and 2.5V rails without an external regulator—the CMOS output swings rail-to-rail, so the logic threshold matches the supply directly. Maximum supply current is 35 mA when enabled; the disable function drops draw to 22 mA max, useful for power-save modes in battery-backed modules or ignition-off states. Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm—the compact footprint fits dense automotive PCBs where board real estate is tight. Surface-mount assembly with standard reflow profiles; no special handling beyond normal MSL precautions. The enable/disable pin can be tied to a GPIO for output gating during system test. ## Active lifecycle and sourcing Product status is Active—in production with no end-of-life notice. Suitable for new designs and volume production. No last-time-buy pressure.","metaTitle":"DSC1121CI2-048.0000T MEMS Oscillator – 48 MHz, AEC-Q100","metaDescription":"DSC1121CI2-048.0000T – 48 MHz MEMS XO, CMOS output, ±25 ppm stability, -40°C to +85°C, AEC-Q100.
