ABSTRACT:
A spread spectrum clock generator includes a plurality of delay cells, wherein each delay cell includes at least one delayer receiving an external clock signal and causing a predetermined propagation delay to the received clock signal, and a controller transmitting a control signal to the delayer to control the propagation delay of the delayer according to a state value of the control signal. With this configuration, the spread spectrum clock generator using a delayer can have a simple circuit configuration and effectively attenuate an EMI.
