How to realize square wave frequency doubling of arbitrary frequency with FPGA
By using PLL in FPGA, the output clock is n/m times of the input clock, where n and m can be integers between 1~256. Of course, no relationship can be realized, one is the performance limitation of FPGA itself, and the other is that the realization of PLL also has a minimum frequency interval, and the frequency difference less than this cardinal number cannot be realized.
