A previous article on jitter (Synch and clock recovery – an analog guru looks at jitter) defined jitter and its various sub-components. The purpose of this note is to answer the question, “So now that ...

With the move to higher data rates, bit-error-rate testing will adopt new multilevel-signal transmissions techniques for better performance, such as PAM-4.

We show that on-die ECC introduces statistical dependence between errors in different bit positions, raising three key challenges for practical and effective error profiling.
