Abstract
A clock detector is provided. The clock detector generally comprises a filter, a first branch, a second branch, a latch, and logic. The filter is adapted to receive a clock signal and is coupled to a low threshold inverter in the first branch and a high threshold inverter in the second branch. The latch is adapted to receive the clock signal and is coupled to the first branch, while the logic is coupled to the node between the first branch and the latch, an output of the latch, and the second branch so that it can output a clock detection signal.
