The 1.7V–3.6V wide supply range simplifies rail selection — a single 3.3V or 1.8V plane powers the oscillator, and the 7.4 mA max supply current keeps the thermal load low enough that no dedicated copper pour is needed under the package.","metaTitle":"DSC1003BI1-040.0000 – Microchip MEMS XO, 40 MHz, CMOS","metaDescription":"DSC1003BI1-040.0000 from Microchip Technology: 40 MHz MEMS XO, CMOS output, ±50 ppm stability, -40°C to +85°C, AEC-Q100 qualified.
