Inphi Introduces Spica – World’s First 800Gbps PAM4 Electro-Optics Platform for Megascale Data Centers and AI Networks
March 09 2020 - 8:00AM
Inphi Corporation (NYSE: IPHI), a leader in high-speed data
movement interconnects, today announced that the company is
sampling its new Spica™ 800G 7nm PAM4 DSP, the world’s first
800Gbps or 8x100Gbps PAM4 DSP to enable 800G optical transceiver
modules in QSFP-DD800 or OSFP form factors. The highly integrated
Spica 800G platform includes Inphi’s high-performance, low power
PAM4 DSPs alongside its companion market leading low power linear
driver and TIAs.
Until today, PAM4 optical modules could only support 400G, which
limits the density available in a single system. Yet the industry
has a relentless thirst for more bandwidth and the desire for lower
power and a smaller footprint. These needs are driving the demand
for high density switching systems. In order to accomplish this, a
new generation of PAM4 DSPs are required to double the bandwidth of
each optical module. Each of these new modules will need to support
up to 800Gbps of bandwidth with a 100Gbps per lane electrical
interface. In turn, a 1 RU 32 port switch will then be able to
support 25.6Tb/s.
In addition, the performance of GPUs, network accelerators and
artificial intelligence (AI) processors continue to skyrocket. This
leap in performance demands higher speed of electrical and optical
interfaces at 100Gbps per lane, to achieve the necessary bandwidth
for connectivity to transfer the vast amount of data between chips
and between AI clusters.
Leveraging seven generations of industry leading PAM4 DSP
development, the Spica 800Gbps PAM4 DSP platform provides the total
solution of electronics for module design. The new low power, PAM4
DSP with integrated 56GBaud driver, enables either 2x400Gbps or
8x100Gbps optical modules with 100Gbps per lane electrical
interfaces. Customers are now able to develop 800Gbps / 8x100Gbps
optical interconnects in a compact form factor for applications
with single mode fibers or multimode fibers. Together with Inphi’s
proven 112Gbps Capella™ SerDes IP for next generation AI processors
and switches, the new Spica PAM4 DSP enables the critical
transition of optical connectivity inside and between AI
clusters.
“The delivery of high-performance, high density and low power
PAM4 800G optical modules is critical to enable the next generation
of networking and AI systems,” said Osa Mok, Chief Marketing
Officer of InnoLight Technology. “Inphi’s ongoing commitment to
innovation and market leadership will help us to stay one step
ahead of the competition and make 800G optical modules a
reality.”
“Inphi is once again breaking a technology barrier to lead our
industry, building on our strong track record of successfully
executing consecutive leaps over technical hurdles because of our
unique approach and our commitment to innovation,” said Eric Hayes,
SVP, Networking Interconnect, Inphi. “As a market leader and the
most reliable electronics partner that customers can depend on, we
are first to bring new products to customers – a hallmark Inphi has
come to be known for, and with best-in-class performance.”
