Product details

This means it survives the thermal cycling of avionics avionics black boxes, downhole drilling tools, and satellite payloads where a quartz oscillator would drift or fail. The MEMS resonator is less sensitive to vibration and shock than a quartz crystal, so the 24.576 MHz output stays locked under the mechanical stress of a missile launch or an engine bay.

Automotive-grade reliability for under-hood designs

If your ECU or ADAS sensor module sees 105°C under-hood temperatures, this oscillator has margin to 125°C. For a battery-backed module, that 13 mA saving extends standby time.

Supply voltage flexibility and packaging

The 2.25V to 3.6V supply range covers 2.5V and 3.3V rails directly — no extra LDO needed. The 6-SMD, No Lead Exposed Pad package measures 7.00mm x 5.00mm with a seated height of 0.90 mm, fitting standard oscillator footprints. The ±50 ppm frequency stability holds the 24.576 MHz clock within 1.2 kHz across temperature and supply variation, sufficient for most Ethernet and audio codec reference clocks.

Frequently asked questions

How can I order the DSC1121AM1-024.5760 or check availability?

We source it through independent distribution; submit an RFQ with your BOM quantity and target lead time, and we will confirm current pricing and delivery from our supply chain.

How do I enable or disable the output of the DSC1121AM1-024.5760?

The oscillator has an Enable/Disable function. When disabled, the supply current drops from a maximum of 35 mA to 22 mA. The exact logic level for enable/disable is defined in the datasheet; typically a high or low pin on the enable input controls the output state.
