Product details

The DSC1123DI2-187.5000: AEC-Q100 qualified for automotive use.

Supply voltage and output compatibility

Supply voltage spans 2.25V to 3.63V, covering 2.5V and 3.3V rails with margin for ripple — no external LDO needed between a 3.3V rail and the oscillator. LVDS output pairs directly with FPGA or ASIC LVDS clock inputs; the differential swing reduces common-mode noise coupling on long board traces compared to single-ended CMOS.

Housed in a 6-SMD no-lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm — the compact footprint frees board space near dense BGA devices. Surface-mount assembly with no lead protrusion.

Availability confirmed at RFQ.

Frequently asked questions

Is DSC1123DI2-187.5000 AEC-Q100 qualified for automotive use?

Yes, it carries AEC-Q100 rating. This qualifies it for automotive-grade applications including under-hood and cabin electronics where vibration and temperature cycling exceed commercial-grade oscillator limits.

Can DSC1123DI2-187.5000 replace a standard quartz oscillator in my design?

Functionally yes — it is a drop-in XO replacement with the same 6-SMD pad layout. The MEMS resonator is more resistant to vibration and shock than quartz, which is why it carries AEC-Q100 qualification.
