Retimers & connectivity silicon (Astera, Credo)
PCIe/CXL retimers and active copper cabling
Astera Labs and Credo supply the retimers, smart cable modules and active electrical cables (AEC) that keep PCIe/CXL and back-end links signal-clean across GB200-class racks. As rack power and link speeds climb, this connectivity silicon becomes a quiet but essential enabler of dense AI systems.
