Product details

AEC-Q100 qualified, this part is specified for automotive applications where the temperature stays within -20°C to 70°C — cabin electronics, infotainment clusters, and ADAS sensor modules that aren't under-hood.

Supply voltage and frequency stability

Supply range is 2.25 V to 3.6 V — covers 2.5 V and 3.3 V rails common in automotive MCU and SoC systems. The ±25 ppm frequency stability keeps the clock within tight tolerance for CAN, Ethernet, and USB timing. Surface-mount 6-SMD package with an exposed pad (7.00 mm x 5.00 mm, 0.90 mm seated height) — the pad helps thermal conduction to the PCB ground plane, though the 35 mA max supply current is modest.

Product status is Active.

Frequently asked questions

Does the DSC1121AE2-025.0000T support enable/disable?

Yes. The enable/disable function is listed as a standard feature. When disabled, the supply current drops to 22 mA max from 35 mA max.

Is the DSC1121AE2-025.0000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 rating — automotive IC qualification covering temperature grade, reliability stress, and PPAP. Suitable for vehicle programs that require an automotive-grade clock source.

Are there alternatives to the DSC1121AE2-025.0000T?

Within the DSC1121 series, other frequency and stability variants exist. A pin-compatible alternative would be another DSC1121 order code at the same frequency and package — confirm the specific frequency, stability, and operating temperature range against your BOM before substituting.
