What this MEMS oscillator does for your clock tree
The MEMS resonator is sealed inside the package, so the oscillator is immune to the shock and vibration that can pull a quartz crystal off frequency. It operates from a 2.25V to 3.6V supply rail, which means it can run directly from a 2.5V or 3.3V regulator without an extra LDO. For a battery-powered sensor node that sleeps most of the time, that standby current is below the self-discharge rate of a CR2032 coin cell.
Industrial temperature range and package fit
The 6-VDFN package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm, so it fits under a low-profile enclosure lid or on a dense mixed-signal board. Surface-mount assembly with a 0.50 mm pitch — the VDFN land pattern is straightforward for a standard reflow profile. No special bake-out or moisture sensitivity level beyond typical MSL 1 handling for MEMS oscillators.
