Non-Transparent Bridge

Enabling Low-Latency CPU-to-CPU Interconnects​

Non-Transparent Bridge

RT = Retimer

Requirements & Challenges

  • CPUs on different server nodes interconnect via back plane, and passing through multiple connectors at PCIe® 4.0 and PCIe 5.0 speeds causes more reflections and insertion loss
  • Low-latency interconnect required between CPUs makes PCIe switches undesirable
  • Each base board has its own clocking domain, so the NTB must support separate reference clocks​​

Aries Retimer Benefits

  • Retimers can be cascaded for extra-long back plane PCBs, or cabled NTB applications​​
  • Protocol-transparent low-latency modes enable < 10 ns added latency between CPUs
  • Supports separate reference clock to accommodate PCIe interconnect​ without needing to send REFCLK across the midplane
