Product details

AEC-Q100 qualified, this part is suited for automotive electronics requiring a reliable reference clock for CAN, Ethernet, or infotainment serial buses — the MEMS resonator eliminates quartz crystal aging and shock sensitivity concerns in under-hood and cabin environments.

Supply voltage flexibility and enable/disable function

Operates from a 2.25V to 3.6V supply, covering common 2.5V, 3.0V, and 3.3V rails without an external regulator — the wide input range simplifies power tree design for mixed-voltage systems.

Listed as Active — Microchip continues production with no announced end-of-life. This is a current design-in part suitable for new BOMs and volume production.

Frequently asked questions

Is the DSC1121BI5-125.0000 AEC-Q100 qualified?

Yes, it carries AEC-Q100 rating, meaning it meets automotive-grade IC qualification for temperature, reliability stress, and PPAP — suitable for under-hood and chassis-domain applications.
