DSM_PLL_reva
展频PLL时钟（SSC）产生电路，可以产生三角波、正弦波或者单频载波(Delta_Sigma Modulator, to be used in TXPLL with SSC modulation. this program
simulates the Spread spetrum clocking scheme. the SSC can be set to triangle wave or sinewave, or you can also set it to be constant frequency which without SSC. the relevant parameters is programmable.
