Astera Labs
Hardware
PCIe protocol-translation gearbox bridging PCIe 6 (Flit-Mode) and PCIe 5 (Non-Flit-Mode) devices for mixed-generation AI infrastructure; two part numbers, both in production.
Active electrical cable modules extending PCIe/CXL signal reach up to 7m for multi-rack GPU-to-GPU clustering, with COSMOS-managed diagnostics and telemetry.
PCIe/CXL signal-integrity retimers (3rd-generation Aries 6 entering volume production) that recover, reclock and retransmit signals to extend reach 3x across AI server baseboards and racks.
CXL 2.0 memory-expansion controllers (E-Series expansion-only, P-Series adds pooling/sharing) supporting up to 2TB CXL memory expansion with 50ns latency for AI and cloud platforms.
AI fabric switch family (X-Series 320-lane memory-semantic switch, P-Series PCIe 6 fabric switches 32-320 lanes) for high-performance AI cluster interconnect, supporting up to 80 accelerators per switch.
Active electrical cables extending 200/400/800G Ethernet signal reach up to 7m for dense AI racks, with COSMOS diagnostics; currently sampling.
3.2T Ethernet/UALink/ESUN signal conditioners (Smart Retimers and Smart Redrivers) on the OCP Signal Conditioner Standard Footprint, interchangeable via 'Smart Swap' without board redesign.
