The MEMS resonator replaces a quartz crystal, giving better shock and vibration tolerance in a smaller footprint — the 6-SMD no-lead package measures just 3.20 mm x 2.50 mm. The MEMS construction also avoids the long lead times sometimes seen with quartz-based oscillators, since the resonator is fabricated in a standard semiconductor fab rather than cut and tuned from a crystal blank. ## Power budget and package fit Maximum supply current is 95 µA, which is low enough for always-on clock domains in battery-operated equipment. The CMOS output is compatible with most MCU and FPGA clock inputs — no level translation needed when the oscillator supply matches the logic supply.","metaTitle":"DSC1101CE2-045.1584T MEMS XO, 45.1584 MHz, CMOS, Active","metaDescription":"Microchip DSC1101CE2-045.1584T: MEMS-based XO, 45.1584 MHz, CMOS output, ±25 ppm stability, -20°C to 70°C, 2.25V-3.6V supply.
