AEC-Q100 qualified MEMS oscillator for automotive clock trees
The DSC1001BI2-048.0000T is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 48 MHz CMOS output with ±25 ppm frequency stability. 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.
