Product details

100 MHz MEMS clock with AEC-Q100 qualification

The AEC-Q100 rating places it in automotive-grade timing — suitable for infotainment, ADAS sensor fusion, or telematics where a quartz crystal's vibration sensitivity is a concern. Operating temperature is -20 to +70 °C, which covers cabin and most under-hood electronic modules that are not directly on the engine block.

Package and mounting — 6-SMD, no lead

Housed in a 6-SMD, No Lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm.

Frequently asked questions

What is the enable/disable function on the DSC1121?

The Enable/Disable pin tri-states the CMOS output when pulled to the disable state, reducing supply current from 35 mA max active to 22 mA max disabled. This is a standard output-enable control, not a shutdown — the internal MEMS resonator and PLL remain powered, so restart latency is minimal.

What is the difference between DSC1121 and DSC1122?

The DSC1121 is a standard MEMS XO with CMOS output. The DSC1122 is a different series within the same family — the key parametric difference is typically output type or supply voltage range. For a pin-compatible alternative within the DSC1121 family, the base product number is DSC1121; other frequency variants share the same 6-SMD footprint.
