The DSC1001CE1-004.8500 is a 4.85 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output clock at ±50 ppm frequency stability across -20°C to 70°C. Its AEC-Q100 qualification places it in the automotive-grade bin — suitable for engine-bay or cabin-domain modules where commercial oscillators would drift out of spec under thermal cycling.
Operating from 1.7V to 3.6V, the oscillator covers 1.8V, 2.5V, and 3.3V logic rails without an external regulator — a single BOM line serves multiple voltage domains. Active draw is 8 mA max; in standby the disable current is 15 µA max, so the part's contribution to the module's ignition-off load is negligible.
Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the compact footprint suits space-constrained automotive ECU or sensor PCBs.
