PCI-SIG® Achieves 32GT/s with New PCI Express® 5.0 Specification

Sponsored by Businesswire

today announced the release of PCI
® (PCIe®) 5.0
specification, reaching 32GT/s transfer rates, while maintaining low
power and backwards compatibility with previous technology generations.

“New data-intensive applications are driving demand for unprecedented
levels of performance,” said Al Yanes, PCI-SIG Chairman and President.
“Completing the PCIe 5.0 specification in 18 months is a major
achievement, and it is due to the commitment of our members who worked
diligently to evolve PCIe technology to meet the performance needs of
the industry. The PCIe architecture will continue to stand as the
defacto standard for high performance I/O for the foreseeable future.”

“For 27 years, the PCI-SIG has continually delivered new versions of I/O
standards that enable designers to accommodate the never-ending
increases in bandwidth required for next generation systems, while
preserving investments in prior generation interfaces and software,”
noted Nathan Brookwood, research fellow at Insight 64. “Over that
period, peak bandwidth has increased from 133 MB/second (for the first
32-bit parallel version) to 32 GB/second (for the V4.0 by16 serial
version), a 240X improvement. Wow! The new PCIe 5.0 standard doubles
that again to 64 GB/second. Wow2. We have come to take this
increased performance for granted, but in reality, it takes a
coordinated effort across many members of the PCI-SIG to execute these
transitions so seamlessly.”

PCIe 5.0 Specification Highlights

  • Delivers 32 GT/s raw bit rate and up to 128 GB/s via x16 configuration
  • Leverages and adds to the PCIe 4.0 specification and its support for
    higher speeds via extended tags and credits
  • Implements electrical changes to improve signal integrity and
    mechanical performance of connectors
  • Includes new backwards compatible CEM connector targeted for add-in
  • Maintains backwards compatibility with PCIe 4.0, 3.x, 2.x and 1.x

The new specification increases performance in the high-performance
markets including artificial intelligence, machine learning, gaming,
visual computing, storage and networking.

Silicon Labs

“One of the outstanding features of the PCI Express 5.0 specification
that sets it apart from other communication standards is the inclusion
of the Refclk performance in the specification. By fine tuning various
system parameters to minimize the amount of reference clock noise that
contributes to data transmission eye closure, PCI-SIG has been able to
retain lower cost reference clock technology than competing standards at
similar data rates. In addition, because PCI-SIG specifies the reference
clock performance as part of the standard, companies like Silicon Labs
which supply PCI Express technology reference clocks for a variety of
applications, can further reduce cost by consolidating volume across
multiple customers even though they use PCIe transceivers from different

“As an active member of the PCI-SIG for more than a decade, Synopsys has
been heavily involved with helping to define the PCI Express 5.0
specification. By providing a complete DesignWare Controller, PHY, and
Verification IP solution for PCIe 5.0 to the market early, we have
already enabled many customers to successfully tape out their advanced
32 GT/s SoCs, with many more expected this year.”

~John Koeter, vice president of marketing for IP, Synopsys


“Tektronix is excited about the role of PCI Express 5.0 technology in
enabling the next generation of datacenters. The doubling of bandwidth
to 32GT/s is core to solving datacenter performance and latency
challenges enabling maximum throughput from the Ethernet links running
at 400Gbps and beyond. As the industry migrates to PCIe 5.0
architecture, prior generations of PCIe architecture must be tested to
maintaining backwards compatibility. It is critical that electrical
physical layer testing is performed by a single test platform approved
by the PCI-SIG for multiple generations. Tektronix is looking forward to
partnering with customers to bring PCIe 5.0 solutions to market with a
single approved hardware test platform that scales across all
generations of PCIe technology.”
