Power integrity of a 4.8Gbps-per-link low-swing single-ended-I/O server memory interface

The power integrity characterization of a high-capacity, compute-server memory system operating at 4.8Gbps-per-link is presented. The design robustness of the low-swing, single-ended signaling is verified as the system has excellent immunity to the noise from simultaneously switching outputs (SSO) and a low power-supply-induced jitter (PSIJ) at the primary chip-package resonance frequency.
