Abstract

Some embodiments include apparatuses and methods having a receiver unit included in a die and a measurement unit included in the die. The receiver unit includes a sampler to sample a first signal based on timing of a first clock signal to generate a second signal. The measurement unit is arranged to sample the first signal based on timing of a second clock signal to provide information for generation of a graph presenting an eye scan of the first signal. The second clock signal has a frequency asynchronous with a frequency of the first clock signal.
