ABSTRACT:
In one aspect, an embodiment provides a clock loss sense and switchover circuit and method in which clock switchover is responsive to loss of a primary signal and to additional switch command signaling. In another aspect, an embodiment provides a clock loss sense circuit and method that utilizes counters and reset signals to compare a primary clock and secondary clock signal.
