DPLL by the phase detector, K addition and subtraction counter mode, pulse subtraction circuit, synchronous detection circuit established, constitute a model N divider. The whole system of the center frequency (ie signal_in and signal_out the code rate of 2 times) to clk/8/N. modulus K K value addition and subtraction counter DPLL decision to establish the accuracy and synchronization time, K is larger, the simultaneous establishment of a long time, synchronization accuracy. contrary is short and low.
