Industry leading performance, lowest power 400G 8:4
gearbox accelerating 400GbE deployments in hyper-scale data center
and cloud networks
Broadcom Inc. (NASDAQ: AVGO) today announced the immediate
availability of its 7nm 400G PAM-4 PHY device, the BCM87400,
designed for data center and cloud infrastructure. Built on
Broadcom’s state-of-art 7nm Centenario™ 112G PAM-4 DSP platform,
the device provides best-in-class 400G 8:4 gearbox performance
while delivering the lowest power, enabling broad market adoption
of 400bE links in hyper-scale datacenter and cloud networks.
Networks are rapidly transitioning to 400GbE pipes as the main
interface connecting the latest generations of high density,
multi-terabit switches with 100G single-lambda optics to support
the increasing demand for higher bandwidth. The exploding need for
high speed connectivity is being driven by emerging technology such
as 5G, AI and machine learning. However, with the current
generation of 16nm 400G PHYs, optical module power dissipation is
approximately 12W. Broadcom’s 7nm 400G PHY solution delivers
significant power savings compared to existing 16nm PHYs, thereby
enabling sub-8W optical modules.
7nm Centenario PAM-4 DSP Highlights
- Industry leading DSP performance and power efficiency enabling
DR4/FR4 optical modules to meet IEEE standards and MSA
specifications
- DSP platform supporting DR/FR optical modules for legacy switch
applications
- Client-side interface compliance to CEI-28G/56G LR
specification supporting long reach (LR) channels
- IEEE 802.3bs standard-compliant KP4 and end-to-end FEC bypass
operation
- Proven PAM-4 architecture supporting multiple optics front ends
including EML, DML and silicon photonics
- Optimized design with proven interoperability with Broadcom
switch ASICs and ASSPs using 28Gbaud PAM-4 and NRZ SerDes
architecture
“With the general availability of 12.8-Tb/s switches such as
Broadcom’s Tomahawk 3, hyper-scale data center operators and cloud
providers will be leveraging the 400GbE ports in these switches to
address increasing demand for higher bandwidth. Our low power 7nm
Centenario PAM-4 DSP is essential to support high density 400G
connectivity using QSFP-DD and OSFP optical modules, accelerating
the adoption of 400GbE network infrastructure,” said Lorenzo Longo,
senior vice president and general manager of the Physical Layer
Products Division at Broadcom. “The currently available 16nm 400G
PHYs have been used to enable engineering prototypes and testing of
100G per lambda optical components. Our 7nm Centenario 400G PHY
enables high volume deployment of 400G optical modules in
hyper-scale data centers.”
“Broadcom demonstrates its technology lead in the PAM4 market
segment with the sampling of the industry’s first 7nm 400G PAM4
PHY,” said Dale Murray, principal analyst at LightCounting Market
Research. “A savings of 4W per 400G optical module in comparison
with currently available CMOS solutions is significant as it will
ease market concerns about power consumption in the transition to
400G optical modules in hyperscale network deployments.”
