Product details

2.488 MHz MEMS oscillator for commercial timing

The DSC1121CE5-002.4880 is a 2.488 MHz XO (Standard) oscillator built on a MEMS resonator rather than a quartz crystal — the MEMS die is sealed at wafer level, which eliminates the crystal aging drift and shock sensitivity that can pull a quartz oscillator off frequency in a high-vibration fan tray or during board reflow.

6-VDFN package and PCB footprint

The 6-VDFN package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight board edges and low-profile enclosures.

Frequently asked questions

What is the exact frequency of the DSC1121CE5-002.4880?

The output frequency is 2.488 MHz.

Is the DSC1121CE5-002.4880 a MEMS oscillator?

Yes, the base resonator is MEMS, not quartz — this gives better shock and vibration tolerance compared to a crystal-based oscillator.
