frequency_divider

The frequency divider is a simple component which objective is to reduce the input frequency. The component is implemented through the use of the scaling factor and a counter. The scaling factor is the relation between the input frequency and the desired output frequency:
scalefact=fin/fout
Assuming an input frequency of 50MHz and provided we need an output frequency of 200Hz, we yield:

Scaling factor for this example. scalefact=50MHz/200Hz=250000.
Therefore, the counter of the frequency divider generates the output signal of 200Hz each 250000 cycles.
