XpressConnect™ PCIe® 6.0 and CXL 3.1 Retimers Address Latency and Signal‑Integrity Challenges in AI Data Centers

MCHP
  • Microchip Technology released XpressConnect PCIe 6.0 & CXL 3.1 retimers to address signal reach & latency constraints in large-scale AI data centers.
  • The retimers extend signal reach beyond conventional PCIe Gen 5 & Gen 6 electrical limits while supporting high-bandwidth connectivity within strict thermal & power budgets.
  • Devices achieve a pin-to-pin latency of under 12 ns, which is approximately 80% lower than standard PCIe 6.0 specifications.
  • Lower latency reduces data stalls in high-density AI clusters, improving the utilization of AI accelerators & GPUs.
  • The solution integrates with Microchip's 3-nm Switchtec PCIe Gen 6 switches, Adaptec SmartRAID controllers, Host Bus Adapters, & Flashtec NVMe controllers.
  • Retimers are compatible with PCIe Gen 3, Gen 4, & Gen 5 platforms to reduce time to market.
  • Devices connect to the ChipLink diagnostic ecosystem for real-time 2D eye capture & four-level pulse amplitude modulation telemetry.
  • The industry-standard, drop-in solution supports flexible link bifurcation configurations (1x16, 2x8, & 4x4) & includes hot-plug support.
  • ChipLink diagnostic tools provide comprehensive debug & analysis via an intuitive graphical user interface using in-band PCIe or sideband signals.
  • XpressConnect retimers are available for purchase directly from Microchip or through authorized worldwide distributors.
