Product details

18.432 MHz MEMS clock for industrial and portable designs

Supply voltage spans 2.25 V to 3.6 V, so it runs directly off a 3.3 V or 2.5 V rail without an external regulator. The ±10 ppm frequency stability keeps the timing tight enough for most serial protocols without a temperature-compensated crystal.

Standby function and current budget

Maximum supply current is 95 µA in active mode — low enough that the oscillator itself won't dominate the sleep-current budget in a battery-powered sensor node.

The 6-VDFN package (2.50 mm x 2.00 mm) keeps the footprint small — useful when board space is tight.

Frequently asked questions

What does the Standby (Power Down) function do on this oscillator?

The Standby pin (active-low, typically) disables the internal oscillator and puts the output into a high-impedance state, dropping the supply current to near zero. It is designed for systems that need to shut down the clock tree during sleep modes without removing the supply rail.
