Crystals and Oscillators at 32.768kHz are primarily used inreal time clock applications.We produce the tuning fork crystals as well as AT-cut oscillators are 32.768KHz in a variety of sizes for your applications.
The tuning fork crystal used in the clock function products, they output frequency by 32.768 kHz is equal to one hertz and to one second by using a 15 stage binary counter.
