Abstract :
An all-digital spread spectrum clock generator is presented. A digital delay matrix (DDM) is used to adjust the delay on a clock, modulating the output and producing an up or down spread. The DDM delay is no longer than one period of the clock. Measured peak clock power reduction is greater than 13dB. The circuit occupies 0.06mm2 in a 0.15mum CMOS process and consumes 7.1mW
