ADIDS32KHZSN#
Overview
The DS32KHZSN# is a temperature-compensated crystal oscillator (TCXO) that provides a highly accurate 32.768 kHz reference frequency in a 16-SOIC package. It is designed to replace standard tuning-fork crystals in applications requiring high stability over a wide temperature range, particularly when integrated into real-time clock (RTC) systems. This device operates from a 5V supply and provides a CMOS-compatible output signal.
Why Choose This Part
The DS32KHZSN# offers a frequency stability of +/-7.5ppm over the -40C to +85C temperature range, which is significantly better than a standard uncompensated crystal. By integrating the resonator and compensation circuitry into a single 16-SOIC package, it reduces component count and simplifies board layout while eliminating the need for manual crystal trimming.
Applications
Key Specifications
Getting Started
To use this device, provide a stable 5V supply to the VCC pin and ground the GND pins as specified in the datasheet. The CMOS output can be connected directly to the OSCI input of a microcontroller or RTC; ensure the load capacitance remains within the specified limits to maintain signal integrity. For prototyping, the 16-SOIC package (0.295 inch width) can be adapted to a breadboard using a standard SOIC-to-DIP breakout board.
