WebApr 14, 2024 · It sounds like you want to implement a fractional clock divider with a digital circuit. Since the division of the clocks is a fraction, the output clock will jitter between two clock periods (in your case between 6 and 7 periods of the 100 MHz clock), but the average will be 100/16=6.25 periods long. WebThe block diagram of such a clock divider is shown in Fig. 2. In the block diagram, the counter increases by 1 whenever the rising edge of clk arrives.
