A method and apparatus for providing system clock failover using a one-shot circuit are disclosed. A process, in one embodiment, is able to detect a clock failure using a one-shot circuit, wherein the clock signals are generated by a first clock circuit. Upon generating a switching signal in response to the clock failure, a system reset signal is asserted for a predefined time period in accordance with the clock failure. After switching a second clock circuit to replace the first clock circuit, the process is capable of resuming the clock signals via the second clock circuit.
