Product details

The DSC1001CI2-018.0000 is a fixed-frequency 18 MHz oscillator built on a MEMS resonator rather than a quartz crystal, delivering CMOS output from a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm.

Automotive-grade qualification and supply flexibility

AEC-Q100 qualification confirms the device meets automotive stress and reliability requirements — a critical check for PPAP submissions and under-hood or chassis-domain deployments.

MEMS vs. quartz — what the resonator choice means for your board

Startup time for MEMS oscillators is typically under 5 ms, versus 10–20 ms for many quartz-based XOs, reducing the time to a stable system clock after power-on.

Frequently asked questions

What is the standby current of the DSC1001CI2-018.0000?

When the standby (power-down) function is active, the maximum supply current is 15 µA. In normal operation the device draws up to 6.3 mA.

Is the DSC1001CI2-018.0000 a direct replacement for a quartz oscillator?

The DSC1001CI2-018.0000 is a MEMS-based oscillator with the same 4-pin SMD footprint as many quartz XOs. It is pin-compatible with standard 3.2 mm x 2.5 mm oscillators, but the MEMS resonator offers better shock/vibration tolerance and faster startup. Confirm the output type (CMOS) and supply voltage range (1.8 V–3.3 V) match your existing BOM before substituting.
