Overview

The SIT1532AI-J4-DCC-32.768E is an ultra-small MEMS-based 32.768 kHz oscillator designed to replace traditional quartz crystals in space-constrained applications. It operates over a wide supply voltage range of 1.5V to 3.63V and features a NanoDrive output to minimize power consumption in battery-powered devices.

Why Choose This Part

This MEMS oscillator eliminates the need for external load capacitors and is highly resistant to shock and vibration compared to quartz tuning forks. Its small footprint and low profile of 0.60mm enable thinner PCB designs without sacrificing frequency stability of 100ppm.

Applications

RTC Reference Clock
Provides a stable time-base for Real-Time Clock modules in ultra-low power microcontrollers.
Wearable Electronics
Fits into tight enclosures for smartwatches and health monitors due to its 1.5mm x 0.8mm CSP footprint.
Battery-Powered IoT
Ideal for sensors that require a continuous sleep clock while maintaining minimal current draw.
