The DSC1001AE1-008.0000 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a fixed 8 MHz CMOS output with ±50 ppm frequency stability across -20°C to 70°C. Rated AEC-Q100, it carries automotive-grade reliability screening — suitable for cabin or chassis-domain electronics where the oscillator must survive temperature cycling and vibration per the automotive qualification flow. The supply voltage range spans 1.8V to 3.3V, letting a single BOM line serve both 3.3V and low-voltage 1.8V logic rails without a regulator change.
Package and board layout note
Housed in a 7.00 mm × 5.00 mm 4-SMD no-lead exposed-pad package, 0.90 mm seated height — the exposed pad should be soldered to a ground-plane thermal relief on the PCB to improve heat transfer and mechanical stability under vibration.
