The MEMS resonator replaces a quartz blank, giving better shock and vibration immunity — a practical advantage for engine-bay and chassis-mounted electronics. ## Supply voltage flexibility and power-down control The oscillator operates from a single 1.8V to 3.3V supply, covering the common digital core and I/O rails. A standby (power-down) function drops the supply current to 15 µA max, useful for battery-backed or ignition-switched modules that need to preserve quiescent draw when the system sleeps. Active current draw is 7.2 mA max at 48 MHz, which is typical for a MEMS oscillator at this frequency and keeps the thermal contribution negligible in a sealed ECU enclosure. The part is suitable for both new designs and ongoing production builds. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1001BI2-048.0000T – Microchip MEMS XO, 48 MHz, CMOS","metaDescription":"Microchip DSC1001BI2-048.0000T MEMS oscillator: 48 MHz CMOS output, ±25 ppm stability, 1.8V–3.3V supply, AEC-Q100 qualified, -40°C to 85°C.
