The post Nothing Out of Reach: The Aries PCIe 7 Family Delivers Copper and Optical Signal Conditioning for AI’s Next Chapter appeared first on ASTERA LABS, INC..

On October 2, 2019, Astera Labs shipped its very first product: the Aries Smart Retimer for PCIe 4.0/5.0. In many ways, Astera Labs and PCIe have matured together, alongside the increasingly realized potential of the AI applications they help power and always in lockstep with our flagship signal conditioning product. PCIe has now advanced to its seventh generation, and the blazing data rates possible in this generation bring with them new infrastructure challenges to solve. Within the rack, every channel is harder to close, loss link margins are razor thin, and finely tuned signal conditioning matters more than ever. At the same time, architects must design for a scale-up domain that has stretched well beyond the rack without adding significant signal loss or latency along the way. So today, we’re announcing the latest generation…
