Clock Divider Circuit. A frequency divider also called a clock divider or scaler or prescaler is a circuit that takes an input signal of a frequency f i n. Displaystyle f out frac f in n where.
Displaystyle f in and generates an output signal of a frequency. Let s assume that the pre defined number is 3 and the output of clock divider clk div is initialized to 0. Displaystyle f out frac f in n where.
For example a clock divider could drive an output low while counting five 100mhz input clock cycles then drive the signal high while counting another five cycles and so on in an endlessly repeating sequence to create a 10mhz clock.
The divider circuit counts input clock cycles and drives the output clock low and then high for some number of input clock cycles. Each stage divided the frequency by 2. The divider circuit counts input clock cycles and drives the output clock low and then high for some number of input clock cycles. A clock divider circuit creates lower frequency clock signals from an input clock source.
