Product details

Package and supply voltage — what fits your board

Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — the footprint matches industry-standard 5.0 x 3.2 mm oscillator pads, so a layout designed for a quartz XO of the same size accepts this MEMS part without a board spin. Supply voltage range is 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails commonly found in automotive and industrial digital systems — no extra regulator needed if the rail sits within that window.

Frequently asked questions

What is the output type and frequency of the DSC1121BI1-125.0038T?

It is a standard XO with CMOS output at 125.0038 MHz. The CMOS logic level is compatible with most MCU and FPGA clock inputs without external level translation.

Is the DSC1121BI1-125.0038T AEC-Q100 qualified?

Yes, it carries AEC-Q100 qualification, meaning it has passed automotive-grade reliability testing for temperature, humidity, and mechanical stress — suitable for under-hood and chassis-domain applications.
