Supply flexibility and standby control
The 1.7V to 3.6V supply range lets this oscillator run from 1.8V, 2.5V, or 3.3V rails without an intermediate regulator — a BOM simplification when the MCU or SoC core voltage is already available.

Frequently asked questions
Does DSC1003CL2-020.0000 have a standby or power-down function?
Yes, the function is Standby (Power Down). When enabled, the supply current drops to 15 µA max, allowing the oscillator to be gated off during system sleep states.
Is DSC1003CL2-020.0000 AEC-Q100 qualified?
Yes, it carries AEC-Q100 ratings, which means it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up — suitable for under-hood and cabin electronics.
