Low Power kHz Crystal Oscillators

Introduction

This line of ultra-low power kHz crystal oscillators offers precise timing with minimal energy consumption, ideal for battery-powered and always-on applications. Available in 1610 (1.6×1.0 mm), 2016 (2.0×1.6 mm), and 3215 (3.2×1.5 mm) surface-mount packages, these oscillators operate at a standard 32.768 kHz and current consumption as low as ~1 µA typ., with fast startup times under 250 ms. Their compact sizes and low current draw make them ideal for integration into wearables, medical devices, IoT sensors, and real-time clocks in MCUs.

Compared to standard crystals or traditional oscillators, these low power XO solutions reduce design complexity, enhance power efficiency, and ensure stable performance across a wide variety of sizes. With CMOS output, broad voltage support, and excellent frequency tolerance (±20ppm), this oscillator series is engineered for designers seeking compact, reliable, and energy-efficient timing components across a wide range of smart and connected devices.
