ADIDS32KHZS#
Overview
The DS32KHZS# is a temperature-compensated crystal oscillator (TCXO) specifically designed to provide a highly stable 32.768 kHz reference clock. It integrates a 32.768 kHz crystal and a temperature sensor into a single 16-pin SOIC package, eliminating the need for external crystal tuning. This part is optimized for 5V systems and maintains a frequency stability of plus or minus 7.5ppm across its full operating temperature range.
Why Choose This Part
The integrated crystal simplifies PCB layout by removing sensitive high-impedance nodes associated with external tuning capacitors. Its temperature compensation circuit guarantees significantly higher accuracy than standard uncompensated crystals, which typically drift severely over temperature. The 16-pin SOIC package provides a robust surface-mount solution for automated assembly in industrial designs.
Applications
Key Specifications
Getting Started
Connect the VCC pin to a stable 5V supply and bypass with a 0.1uF ceramic capacitor. The 32.768 kHz CMOS output can directly drive the OSCI input of a microcontroller or RTC. Ensure the thermal pad areas are handled according to the datasheet to maintain optimal temperature sensing accuracy.
