The MEMS resonator gives this oscillator a significant reliability edge over quartz in high-shock and high-vibration environments — no crystal to crack or age-shift under thermal cycling. With a 2.25V to 3.6V supply range, it can be powered directly from a 3.3V or 2.5V rail without an intermediate regulator, saving a component and a PCB via. ## Enable/disable function and output drive CMOS output drives standard logic families directly; the 35mA max supply current is the total device draw at full output load, so budget this into the rail's current capacity. Housed in a 6-VDFN package measuring 2.50mm x 2.00mm with a 0.90mm seated height, this oscillator fits tight PCB layouts — the 0.098\" x 0.079\" footprint is roughly the size of a 0805 capacitor.","metaTitle":"DSC1121DM2-014.7456 MEMS Oscillator","metaDescription":"Active Microchip DSC1121DM2-014.7456 XO (Standard) with CMOS output, 14.7456 MHz, ±25ppm stability, -55°C to 125°C range, 6-VDFN package.
