This document provides application-based criteria to assist system developers in selecting between 25G/28G retimers and redrivers. Functional background and description of relevant performance parameters and features for these devices are included to facilitate part number comparison and selection. Channel insertion loss, networking standard compliance needs and link training support are all reviewed in the context of component selection of retimers versus redrivers to achieve signal conditioning and link reach extension.
