Abstract
An apparatus includes a clock signal input, a sampling circuit, and an estimation circuit. The clock signal input receives N time measurements. A time measurement denotes a respective portion of a given cycle of a clock signal. The sampling circuit is to generate a first sampled window from the clock signal input. The first sampled window includes an accumulation of the N time measurements. The sampling circuit is to generate a second sampled window from the clock signal input including an accumulation of a plurality of products. The estimation circuit is to estimate the frequency or period of the clock signal based upon the first sampled window and the second sampled window.
