Product details

Why this MEMS oscillator exists

A quartz crystal oscillator requires external load capacitors and a startup time that can stretch past 10 ms. The DSC1001BE1-025.0000T uses a MEMS resonator instead, delivering a 25 MHz CMOS clock from a single 4-SMD package with no external timing components — the supply decoupling caps are all it needs. The supply voltage range spans 1.8V to 3.3V, so the same part number works on a 1.8V MCU rail or a 3.3V SoC rail without a separate level translator.

Automotive-grade clock source

Standby mode for low-power systems

This makes the DSC1001BE1-025.0000T a natural fit for battery-powered automotive modules like a TPMS receiver or a keyless-entry controller that spends most of its life asleep.

Frequently asked questions

Is the DSC1001BE1-025.0000T compatible with a 3.3V supply?

Yes. The supply voltage range is 1.8V to 3.3V, so it runs directly on a 3.3V rail without an external regulator or level shifter.

Does the DSC1001BE1-025.0000T have a standby (power down) function?

Yes. The standby function is listed as a feature. When disabled, the supply current drops to 15 µA max, compared to 6.3 mA max when active.

Is the DSC1001BE1-025.0000T rated for automotive (AEC-Q100) applications?

Yes, it carries an AEC-Q100 rating. The operating temperature range is -20°C to 70°C, which suits cabin and infotainment systems but not full under-hood ambient.
