Frequency Division Using Fractional Clock Divider with DSM
Open the model
fractionalClockDivider_w_DSM. The model consists of a Pulse Generator and a Fractional Clock Divider with Accumulator block.
The period of the incoming pulse at the clk in port is
4e-7 s. So, the incoming signal has a frequency of
2.5 MHz. The div-by value is set at
2.5. The clock divider uses a second order delta sigma modulator.
Run the simulation for
1e-4 s. The frequency of the output signal is
