Product details

12.288 MHz MEMS oscillator with ±25 ppm stability

The DSC1121AI2-012.2880: Its 2.25V to 3.6V supply range allows it to run directly from a 2.5V or 3.3V rail without an external regulator, and the Enable/Disable function lets the system gate the clock for power savings.

6-SMD package – board layout notes

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, this oscillator fits the standard 7x5 mm footprint common to many quartz oscillators – a direct drop-in replacement for existing designs using that form factor.

Frequently asked questions

What is the output drive capability of DSC1121AI2-012.2880?

Design engineers need to ensure the oscillator can drive the input capacitance of downstream logic without signal degradation.

What is the price of DSC1121AI2-012.2880 in 1000-piece quantities?

Sourcing buyers need volume pricing to build accurate BOM costs and negotiate with distributors.

Which distributors have DSC1121AI2-012.2880 in stock?

Urgent procurement decisions depend on real-time stock visibility to avoid production delays.

Is DSC1121AI2-012.2880 a direct replacement for standard quartz oscillators of the same footprint?

Maintenance techs and design engineers need to know compatibility when substituting MEMS devices for quartz in existing designs.

What is the operating temperature range for DSC1121AI2-012.2880?

Reliability in harsh environments depends on the specified temperature range; missing this spec can cause field failures.

Can DSC1121AI2-012.2880 be ordered as cut tape or full reel?

Sourcing buyers need to confirm packaging options to match their assembly requirements and minimize handling costs.
