Implementation of PC Frequency Divider Based on FPGA
Zeng Ju-rong · Journal of Yibin University · 2011
A multiple frequency circuit which can multiply the frequency of clock signal to realize the integer frequency divider with equal duty cycle was designed.The dual-modulus prescaler was used to realize the decimal frequency divider.The way of accumulating the decimal part to mix the N and N+1 divider was adopted in order to diminish the phase fluctuation of out single.The simulation indicates that the PC frequency divider can realize the arbitrary division of signal with the frequency within 100MHz.
