LVCMOS output is the standard single-ended clock interface for most MCUs, FPGAs, and SoCs — no level translation or AC-coupling needed for a typical 3.3V or 2.5V logic input. ## Package and PCB layout note The 4-pin footprint is straightforward to hand-solder or reflow; the exposed pad is the only thermal challenge — a stencil aperture covering 50-70% of the pad area prevents solder voids. ## Current consumption and power budget Maximum supply current is 7.5 mA — low enough for battery-operated equipment or thermally constrained designs; at 3.3V that's under 25 mW, negligible in a multi-rail system.","metaTitle":"DSC1522AA3A-25M00000 MEMS Oscillator - Microchip - 25 MHz","metaDescription":"DSC1522AA3A-25M00000 XO (Standard), LVCMOS output, 25 MHz, ±20 ppm stability, -40 to 125°C, 2.5-3.3V supply.
