Embodiment Construction
[0029] 1. Part selection
[0030] A. CPLD4 uses EPM1270T144C5 from ALTERA company;
[0031] B, 24-bit counter module 1 is implemented in Verilog HDL language inside CPLD4;
[0032] C. The 23-bit preset counter module 2 is implemented in Verilog HDL language inside CPLD4;
[0033] D, D flip-flop module 3 is realized with Verilog HDL language inside CPLD4.
[0034] 2. Specific implementation methods
[0035] Depend on figure 1 As shown, the implementation steps of a phase shifting method are as follows:
[0036] ①Input signal F IN Connect to the clock input terminal of the n-bit counter M1, and the counter M1 outputs two synchronous square wave signals, one of which is F IN×1 / N , the other signal is F IN×2 / N , F IN×1 / N The frequency is F IN one-nth of N, and F IN×2 / N The frequency is F IN×1 / N Twice of , where N≤2 n And the value of N is determined by the control parameters of the counter M1, F IN×1 / N That is, the square wave signal to be phase-shifted;
[0037] ②In...
