MEMS oscillator with AEC-Q100 grade
The DSC1001DI2-054.0000T is a 54 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering CMOS output in a 4-SMD, no-lead package. Its AEC-Q100 rating means it's qualified for automotive stress and reliability requirements — suitable for under-hood or cabin electronics where vibration and temperature cycling are the norm.
Supply flexibility and standby power-down
Operates across a 1.8V to 3.3V supply range, so the same oscillator can be reused across 1.8V, 2.5V, or 3.3V logic domains without a separate regulator. The standby (power-down) function drops supply current to 15 µA max — useful for battery-backed modules that need to wake on a timed interval. Active current draw is 7.2 mA max at 54 MHz, keeping the thermal footprint low in dense PCB layouts.
Temperature range and frequency stability
The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal, which matters for engine-bay or chassis-mounted ECUs.
