Product details

100 MHz MEMS clock for industrial timing

Its ±50 ppm frequency stability covers most serial-interface and controller clock trees without the tighter tolerance (and higher cost) of a TCXO.

Supply voltage spans 2.25 V to 3.5 V, covering both 2.5 V and 3.3 V digital rails with headroom — no separate regulator needed for the oscillator in most designs. It fits outdoor telecom enclosures, factory automation panels, and under-hood electronics that see ambient heat but not engine-block extremes.

Package and footprint details

Housed in a 6-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that suits dense PCB layouts.
