Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, this oscillator is a drop-in replacement for standard 7x5 mm crystal oscillators — the same footprint, no board spin.","metaTitle":"DSC1121AM2-040.0000T MEMS Oscillator","metaDescription":"DSC1121AM2-040.0000T MEMS XO from Microchip: 40 MHz, CMOS output, AEC-Q100 qualified, -55°C to +125°C, 2.25V-3.6V supply.

The MEMS resonator inside is more shock-resistant than quartz, so it handles vibration environments better, but the electrical interface is identical."},{"question":"Does the DSC1121AM2-040.0000T work on a 3.3V supply?","answer":"Yes — the supply voltage range of 2.25V to 3.6V covers both 2.5V and 3.3V rails directly.
