Abstract
Embodiments herein describe a glitch detector circuit (and method of operation) for detecting glitches in a clock signal. In one embodiment, the glitch detector includes a shift register that samples the reference clock using a clock signal output by a PLL. The value in a first memory element of the shift register can be sampled to previous values that were stored (and then bit shifted) in the shift register. If there is a mismatch, the glitch detector indicates there was a clock glitch in the reference clock, and a corrective action can be performed.
