Product details

MEMS XO with automotive-grade qualification

The DSC1121DL2-025.0000 is a 25 MHz MEMS-based XO (Standard) with CMOS output, rated AEC-Q100 for automotive reliability. The MEMS resonator replaces a quartz crystal, giving better shock and vibration immunity — relevant for engine bay or chassis-mounted ECUs where a quartz crystal might fracture under continuous vibration.

Supply voltage and temperature range

Operates from 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails without an external LDO.

Enable/Disable function and package

Includes an Enable/Disable pin (tri-state output when disabled) — useful for power-cycled subsystems or test modes where the clock must be gated without a separate buffer. Housed in a 6-SMD no-lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm, it fits tight board stacks in handheld or space-constrained modules.

This part is suitable for both new designs and ongoing production.

Frequently asked questions

Is DSC1121DL2-025.0000 a direct replacement for standard 25 MHz quartz oscillators?

It is a functional replacement for a 25 MHz CMOS-output XO in a 6-pin no-lead package, but the MEMS resonator has different startup characteristics and supply voltage range (2.25V–3.6V). Verify that your existing oscillator's supply voltage, output type, and enable polarity match before substituting.

Is DSC1121DL2-025.0000 AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, making it suitable for automotive applications requiring the associated reliability stress and PPAP documentation.
