WebThe obvious thing: if you want to divide a 50 MHz clock to 1 Hz, you need to divide by 50 million, so you need to count to 50 million, not to 25 million. The finer points: in a production design you don't want to run a counter off a fast clock to generate a slower clock. A frequency divider, also called a clock divider or scaler or prescaler, is a circuit that takes an input signal of a frequency, $${\displaystyle f_{in}}$$, and generates an output signal of a frequency: $${\displaystyle f_{out}={\frac {f_{in}}{n}}}$$where $${\displaystyle n}$$ is an integer.
