The 2.25V to 3.6V supply range means it can run from a 2.5V or 3.3V rail without an extra regulator, simplifying the power tree. The MEMS resonator base inherently resists shock and offers faster startup than a quartz crystal — no load-capacitance matching or negative-resistance margin calculation needed. The 6-SMD no-lead package (5.00mm x 3.20mm footprint, 0.90mm seated height) is a standard MEMS oscillator pinout, compatible with many quartz oscillator footprints for drop-in replacement.","metaTitle":"DSC1121BI2-016.3840T MEMS XO 16.384 MHz CMOS - Microchip","metaDescription":"Active MEMS oscillator, 16.384 MHz CMOS output, 2.25V-3.6V supply, ±25 ppm stability, -40°C to 85°C.
