Abstract
An apparatus and method are disclosed for initiating automatic recovery from a signal loss. A frequency division circuit receives a system clock signal, and generates an output signal having a lower frequency than the clock signal. An input detection circuit receives an asynchronous input signal from an external source and outputs a third output signal that indicates whether or not the asynchronous input signal is present or absent within a prescribed detection interval. A recovery circuit receives the system clock signal and the third output signal, and outputs a recovery signal that indicates a loss of the asynchronous input signal over a predetermined length of time. The recovery signal is used as a trigger to initiate a recovery process by the system.
