Frequency Divider Ic. The heart of this circuit is a ne555 timer ic. The output frequency produced by the multivibrator depends on three components r1 r2.
The ic possesses an oscillation frequency ranging from 670 to 680 hz. A free running oscillator which has a small amount of a higher frequency signal fed to it will tend to oscillate in step with the input signal. So in this tutorial we are going to make frequency divider using 555 timer cd4017 ic which divides the frequency by 2 or 4.
The negative edge of the applied signal triggers the timer and the c1 capacitor starts charging.
In an injection locked frequency divider the frequency of the input signal is a multiple or fraction of the free running frequency of the oscillator. Ic 555 was wired as an astable multivibrator and this forms the source of the clock pulse. Clock divider devices when used in divide by 1 mode can also function as a fanout buffer.
