The DSC1003DE1-048.0000T is a 48 MHz MEMS-based XO (standard oscillator) from Microchip's DSC1003 series, delivering a CMOS output across a wide 1.7-3.6 V supply range — one BOM entry covers 1.8 V, 2.5 V, and 3.3 V logic rails without a separate level translator. AEC-Q100 qualification means this part passed automotive-grade reliability stress tests — suitable for cabin or chassis-domain ECUs where the ambient stays within the -20 to 70 °C operating window.
Rated supply voltage is 1.7 V to 3.6 V. At 1.8 V nominal the oscillator runs within spec — no external regulator needed if the rail is clean. The CMOS output swings rail-to-rail, so it drives 1.8 V logic inputs directly and 3.3 V inputs with a series resistor for overshoot control. Maximum supply current is 7.4 mA; standby mode drops to 15 µA via the Standby (Power Down) function — useful for battery-backed modules that need to shut the clock tree when idle.
