Do you know why 32.768KHz is used for clock function? And this frequency is used in a wide range of applications involving real time clock functions. We call them to be clock crystal.
Right!
1. Because THIS frequency in crystal oscillator working can be a perfect policeman to control the time and management of electronic circuits.
2. Because this 32.768KHz gives exactly 215 cycles per second, which is perfect for using in digital circuits with a binary counter such as a 16 bit counter.
We at A-Crystal main manufacture 32.768KHz crystals which is high reliability crystal oscillators
