Retimers address latency and signal integrity
As AI workloads scale, data center architects are increasingly constrained by limited signal reach and rising latency, potentially leaving valuable memory resources underutilized across large GPU clusters. These challenges are amplified as interconnect speeds increase.
In response, Microchip has released XpressConnect PCIe 6.0 and CXL 3.1 retimers to enable memory expansion and resource disaggregation in large-scale AI fabrics.
The retimers are designed to extend signal reach beyond conventional PCIe Gen 5 and Gen 6 electrical limits, enabling more flexible system designs across complex baseboards, riser cards and labled interconnects. The retimers achieve a pin-to-pin latency of less than 12 ns, approximately 80 per cent lower than PCIe 6.0 specifications.
Microchip’s corporate VP and GM of data center solutions business unit, Brian McCarson, said: “Our XpressConnect retimers are designed to act as the high‑performance nerve center of the AI server, helping customers build more scalable, power‑efficient fabrics by reducing latency and improving connectivity across dense GPU clusters.”
