Abstract
Systems and methods for controlling clock rates of circuits are provided. The systems and methods, collectively referred to as clock rate control, generate a clock rate control parameter from data of one or more fuses. The clock rate control detects any overclocked signal of received clock signals by determining a clock signal is running faster than a threshold represented by the clock rate control parameter. The clock rate control controls a circuit clock rate using a selected signal of the clock signals that is not an overclocked signal.
