The MEMS resonator eliminates quartz crystal startup delays and offers superior shock resistance compared to a standard quartz oscillator, a practical advantage in high-vibration environments like engine bays or avionics. Operating from a 2.25V to 3.6V supply, this oscillator covers 2.5V and 3.3V logic rails without an external regulator — a single rail powers the device. Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the footprint is compatible with standard reflow soldering profiles.","metaTitle":"DSC1121AM2-050.0000T MEMS Oscillator – 50 MHz, CMOS","metaDescription":"Microchip DSC1121AM2-050.0000T: 50 MHz XO, CMOS output, MEMS resonator, AEC-Q100 qualified, -55°C to +125°C, 2.25V–3.6V supply.
