Breakthrough Technology from Astera Labs Doubles PCI Express Signal Reach in Servers

Sponsored by Businesswire

Labs Inc.
, a maker of purpose-built connectivity solutions for
intelligent systems, today announced the industry’s first Peripheral
Component Interconnect PCI Express® (PCIe®) 5.0 retimer technology,
specifically designed to remove performance bottlenecks and signal
integrity challenges in next-generation servers. This breakthrough,
system-aware technology makes it possible for hyperscale data center
system designers to create a robust server connectivity backbone tying
together processors, workload accelerators and storage nodes over
diverse system topologies at speeds up to 32 gigatransfers per second

Servers have been operating with PCIe 3.0 technology for many years.
With PCIe 4.0 processors entering the market and the PCIe
5.0 specification now released
, system designers are rapidly gearing
up for the increased bandwidth enabled by these new standards. “At 16
and 32 GT/s, retimers play a crucial role to achieving diverse system
topologies and accelerating the shift to blazing-fast speeds,” said Al
Yanes, PCI special interest group (SIG) chairman and president.

“Heterogeneous computing and workload-optimized platforms are redefining
the connectivity backbone in the next generation of servers. Specialized
semiconductors will help enable this high-speed connectivity backbone
and accelerate technology adoption,” said Jitendra Mohan, CEO at Astera
Labs. “Our system-aware retimers are designed to empower system
designers to easily upgrade from PCIe 4.0 to PCIe 5.0 technology and
achieve plug-and-play interoperation without compromising interconnect
topologies even at 32 GT/s speeds.”

“The explosion of data and new compute-intensive workloads, like
artificial intelligence and machine learning, is driving the need for
faster and lower-latency interconnects in data-centric systems,” said
Amber Huffman, Intel fellow, Data Center Group. “Intel is embracing and
leading the transition with its support for the new PCIe 5.0
specification and the announcement of Compute Express Link (CXL)
technology. We are excited that Astera Labs has entered the ecosystem to
develop purpose-built connectivity solutions to enable seamless adoption
of these technologies.”
