What this MEMS oscillator does on the board
The DSC1001CI1-012.8000 is a fixed-frequency XO (Standard) clock source built around a MEMS resonator rather than a quartz crystal. The MEMS base resonator gives this oscillator better shock and vibration tolerance than a quartz crystal — useful for automotive and industrial environments where mechanical stress is present.
AEC-Q100 qualification and automotive fit
Rated AEC-Q100, this oscillator is qualified for automotive-grade applications.
Power budget and standby mode
Maximum supply current is 8 mA during active operation. The Standby (Power Down) function drops current to 15 µA max — low enough to leave the oscillator powered from a battery-backed rail without draining the cell during system sleep.
Package and supply voltage flexibility
Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts. Supply voltage range is 1.7 V to 3.6 V, covering 1.8 V, 2.5 V, and 3.3 V logic rails without an external regulator.
