Why 32.768Khz crystal?

Do you know why 32.768KHz is used for clock function? And this tuning fork oscillator frequency is used in a wide range of applications involving real time clock functions.



Right!


  • Because THIS frequency can be a perfect policeman to control the time and management of electronic circuits.
  • 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.You can get a precise 1 second period (1Hz frequency) by using a 15 stage binary counter.
