Why this MEMS oscillator exists
The DSC1001CI2-035.4689: Unlike a quartz crystal oscillator, the MEMS resonator inside this part is inherently more resistant to shock and vibration — a real advantage in automotive and industrial environments where a quartz can micro-crack or drift under mechanical stress. The AEC-Q100 rating means this part has passed the automotive-grade reliability stress tests — temperature cycling, ESD, latch-up, and extended life — so it is qualified for under-hood and cabin electronics where a standard commercial oscillator would be a single-point failure risk.
Supply voltage and power budget
The supply range spans 1.8V to 3.3V, which covers the common logic rails in automotive ECUs and industrial controllers. Maximum supply current is 7.2 mA — low enough that a standard 100 mA LDO can power this plus several other loads without thermal concern. When the Standby (Power Down) function is asserted, the disable current drops to 15 µA, letting the oscillator sit on a battery-backed rail without draining the cell.
