Product details

The DSC1001BE1-125.0000T is a MEMS-based XO (Standard) producing a 125 MHz CMOS output with ±50 ppm frequency stability, covering the supply range from 1.8 V to 3.3 V.

Supply flexibility and standby power savings

Maximum active supply current is 8.7 mA at 125 MHz — a low-power figure for a 125 MHz CMOS output, keeping thermal rise minimal in the 4-SMD package.

It fits indoor equipment, passenger cabin electronics, and test gear, but not engine-bay or outdoor telecom enclosures where -40 °C ambient is expected.

Frequently asked questions

Is the DSC1001BE1-125.0000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, meaning it has passed automotive-grade reliability testing (temperature cycling, ESD, latch-up). This qualifies it for automotive applications where the ambient temperature stays within its -20 °C to 70 °C range.

Can the DSC1001BE1-125.0000T run on a 1.8 V supply?

Yes. The supply voltage range is 1.8 V to 3.3 V, so it works on a 1.8 V rail without a level translator. The CMOS output swings rail-to-rail at the selected supply voltage.

What is the difference between the DSC1001 and DSC1002 series?

The DSC1001 series is a standard XO with CMOS output, while the DSC1002 series typically offers a different output type (e.g., LVDS or HCSL) for differential clocking. For a CMOS 125 MHz application, the DSC1001 is the correct choice.
