Product details

The operating temperature range spans -40°C to 105°C, placing it in the AEC-Q100 Grade 1 band. That covers under-hood electronics, engine-bay ECUs, and outdoor telecom gear where a standard commercial XO would drift out of spec or fail.

Supply flexibility and frequency stability for mixed-voltage boards

The supply voltage accepts 2.25V to 3.6V, so the same part can serve a 2.5V FPGA bank and a 3.3V MCU rail without a separate regulator. That disable current is higher than a typical LDO shutdown, but the oscillator itself is the load — the board can gate the clock to save power without a separate switch.

Package, footprint, and board-level fit

The 6-SMD, No Lead Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm.

Frequently asked questions

Is the DSC1121AL2-025.0000 AEC-Q100 qualified?

Yes, the Ratings field lists AEC-Q100. This means the oscillator has passed the automotive-grade qualification tests for temperature cycling, ESD, latch-up, and reliability stress per the AEC-Q100 standard. It is suitable for under-hood and chassis-domain applications where a standard commercial XO would not be accepted.
