Product details

156.25 MHz LVDS MEMS oscillator – active, industrial temp

Supply voltage spans 2.25V to 3.63V, drawing 32 mA max during operation and dropping to 95 µA in standby (power-down) mode, making it suitable for power-sensitive or intermittent-duty designs. The MEMS base resonator provides faster startup and better shock/vibration tolerance than quartz, a practical advantage in industrial, telecom, and outdoor equipment where mechanical stress is a concern.

Standby function and supply flexibility

The standby (power down) function disables the output and drops current consumption to 95 µA max, allowing the oscillator to be gated off during system sleep without removing the supply rail. The wide 2.25V–3.63V supply range covers common 2.5V and 3.3V rails, simplifying integration without an external LDO.

Frequently asked questions

What is the difference between a MEMS oscillator and a crystal oscillator?

A MEMS oscillator uses a silicon micro-electromechanical resonator instead of a quartz crystal. The DSC1103AI5-156.2500's MEMS base offers faster startup, better shock/vibration tolerance, and typically wider frequency stability over temperature compared to a basic quartz XO, though quartz still dominates for ultra-low phase-noise requirements.
