In this video, Casey Morrison gives a quick tutorial on PCIe® Retimers – What do they do? When to use them? What key features to look for? PCI-SIG compliance requirements, etc.
Signal-integrity challenges will be significant in PCIe Gen 4.0 and Gen 5.0 due to increased data rates. A PCIe Retimer is a cost-optimized option to provide more margins and enable a robust link. Compliance tests meeting electrical and protocol specifications, latency, small total footprint, power consumption, bifurcation capacity, in-band and side-band diagnostics are key features system designers should look for in Retimers.
