Product details

MEMS oscillator, not a quartz crystal

The output is a clean CMOS clock at 10 MHz with ±25ppm frequency stability, so it drops straight into a digital input without an external load capacitor or feedback resistor.

That temperature band suits under-hood and cabin-mounted ECUs, ADAS sensor modules, and infotainment head units where a quartz oscillator might drift or fail under vibration. The supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without a separate LDO — one less component in the power tree.

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. Maximum supply current is 35mA when enabled and 22mA when disabled — the disable current is still present because the internal MEMS and PLL remain biased, so a hard power switch saves more power if the clock is off for long periods.

Frequently asked questions

How can I order DSC1121AI2-010.0000T or check availability?

Submit an RFQ for lot-specific lead time and price.

Does DSC1121AI2-010.0000T have an enable/disable function?

Yes, the device includes an enable/disable function. When the enable pin is pulled low, the output enters a high-impedance state while the internal oscillator remains powered — the disable current is 22mA max, versus 35mA max when enabled.

Is DSC1121AI2-010.0000T AEC-Q100 qualified?

Yes, it is rated AEC-Q100, the automotive IC qualification standard.

Is DSC1121AI2-010.0000T a crystal or MEMS oscillator?

It is a MEMS-based oscillator. The base resonator is a silicon MEMS structure, not a quartz crystal — the part is a complete oscillator module, not a bare crystal requiring external load capacitors.

What is the output frequency tolerance of DSC1121AI2-010.0000T?

The frequency stability is ±25ppm over the full operating temperature range and supply voltage variation.
