Product details

It is suited for engine control units, transmission sensors, and ADAS camera modules where a quartz oscillator's shock sensitivity would be a risk.

Wide supply and stability margins

The supply voltage range spans 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an intermediate regulator. This simplifies the power tree in mixed-voltage designs like an FPGA with a 2.5V bank and a 3.3V PHY. The MEMS resonator also resists 50,000 g shock, per the DSC1121 family datasheet, which matters for downhole drilling tools or military munitions fuzing.

Design-in is safe for new projects, and repeat orders face no allocation risk typical of older quartz XOs.

Frequently asked questions

Is the DSC1121BM1-025.0000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, which means it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up. It is suitable for under-hood and chassis-domain applications.

Can the DSC1121BM1-025.0000T replace a standard quartz oscillator?

Yes, it is a drop-in replacement for a 25 MHz quartz XO in the same 6-SMD no-lead footprint. The MEMS resonator offers better shock and vibration immunity, and the wider temperature range covers industrial and automotive environments where quartz may struggle.

What is the output type of the DSC1121BM1-025.0000T?

The output is CMOS, which is compatible with most digital logic families including LVCMOS and standard 3.3V or 2.5V I/O banks.
