Product details

The supply range spans 2.25V to 3.6V, so the same oscillator can run on a 2.5V or 3.3V rail without a separate level translator — a BOM simplification for mixed-voltage designs.

The disable current is three orders of magnitude lower, so the standby savings are real for a sensor node that sleeps most of the time.

Package and layout: 6-VDFN exposed pad

Housed in a 6-VDFN exposed pad package measuring 7.00 mm × 5.00 mm with a seated height of 0.90 mm. The 0.90 mm height keeps the oscillator low-profile for mezzanine or card-edge assemblies where component clearance is tight.

Frequently asked questions

How does a MEMS oscillator compare to a standard quartz oscillator?

A MEMS oscillator uses a silicon micro-electromechanical resonator instead of a quartz crystal. The MEMS version typically offers faster startup, better shock and vibration tolerance, and a smaller footprint. The DSC1101AL5-049.1520 is a MEMS-based XO (Standard) with CMOS output.
