Abstract

With the increase of data rate, signal integrity (SI) becomes a bigger challenge for printed circuit board (PCB) designs. Power noise as well as signal loss, inter-symbol interference (ISI), crosstalk needs to be taken into account to ensure a good quality signal design. In this paper, a design case is shared where power noise greatly impacts SATA performance and leads to hard disk (HDD) disconnection. Noise source and noise coupling path are root-caused with simulation and measurement data. And learnings from this case is summarized for future attention.
