125 MHz LVPECL MEMS oscillator for industrial clock trees
Supply voltage spans 2.25V to 3.6V, so it runs directly off a 2.5V or 3.3V rail without an extra regulator.

Product details
Frequently asked questions
Does the DSC1102BI2-125.0000T come in a lead-free package?
The evidence does not explicitly state RoHS or lead-free status. The 6-SMD, No Lead package is compatible with lead-free reflow profiles, but confirm with the datasheet for full compliance details.
Is the DSC1102BI2-125.0000T a MEMS oscillator?
Yes — the base resonator is MEMS, not a quartz crystal. MEMS oscillators typically offer better shock and vibration resistance and faster start-up than quartz-based XOs.
What is the function of the standby pin on the DSC1102BI2-125.0000T?
Standby (Power Down) — when asserted, it disables the output and reduces supply current to 95 µA max. This is useful for battery-operated systems that need to conserve power between active periods.
