MaxLinear’s Telluride PAM4 SoC Demonstrated by Molex for New 100G and 400G Data Center Optical Modules

  • Molex has built and demonstrated new transceiver modules for data
    center interconnects using MaxLinear PAM4 DSPs

CARLSBAD, Calif.–(BUSINESS WIRE)–MaxLinear, Inc. (NYSE: MXL), a leading provider of radio frequency (RF),
analog and mixed-signal integrated circuits for the connected home,
wired and wireless infrastructure, and industrial and multimarket
applications, today announced Molex, LLC has demonstrated MaxLinear’s
“Telluride” (MxL935xx) pulse-amplitude-modulation (PAM4) digital signal
processing (DSP) systems-on-chip (SoCs) for next generation 400G-DR4 and
100G-DR optical modules.

Molex’s 400G-DR4 and 100G-DR modules will be part of a broad offering of
data center connectivity solutions leveraging copper and optics, both
inside and outside the rack. Molex’s knowledge and experience in data
center connectivity drive industry standards, including QSFP-DD, QSFP28,
SFP-DD and 100G Lambda. Molex support for the Open19 Initiative with
the Molex Impel Customized Data Cable solution aims to establish a new
open standard for data center servers by delivering a flexible, scalable
and secure platform.

MaxLinear’s MxL935xx Telluride family of SoCs are key components in the
development of high-speed hyperscale data centers based on 100Gbps
single lambda optical interconnects. The MxL935xx Telluride family of
chips are the world’s first DSP SoCs with integrated electro-absorption
modulated laser (EA-EML) drivers for 100/400Gbps optical interconnects
and breakout mode clocking support for 400Gbps DR4 optical modules. The
MxL935xx allows companies like Molex to develop a 100/400Gbps optical
interconnect module in a compact form factor for intra-data center
applications with a transmission distance up to 2 kilometers.

“With the exponential growth of data traffic within hyperscale cloud
networks, there is massive demand to deploy higher speed networks,
making 100/400Gbps transceiver modules like these essential in
next-generation hyperscale data centers,” said Will Torgerson, Vice
President and General Manager of MaxLinear’s High-Speed Interconnect
Group. “Telluride is the industry’s only solution designed with an
integrated EA-EML driver and break-out mode support to simplify complex
module designs while offering superior link-margin performance in a
low-power consumption SoC.”

Technical Details

The Telluride family features several operating modes, allowing them to
interface with multiple generations of switch ASICs (128x25G NRZ,
256x25G NRZ or 256x50G PAM4). This versatility enables 3.2Tbps, 6.4Tbps
or 12.8Tbps front panel capacity per data center rack unit. These SoCs
are suitable for use within QSFP-DD, OSFP and COBO module form factors.

The integrated laser driver delivers greater than 1.8V of single-ended
driver output swing necessary for EA-EML lasers. This output swing
easily meets the optical modulation amplitude (OMA) specification
requirements across the wide operating temperature and bias ranges of
all EA-EML lasers. The chip package also includes all the high frequency
components required for driver and modulator biasing.

Asynchronous breakout mode clocking is an essential feature for
hyperscale data center customers initiating 400G DR4 deployments.
MaxLinear’s 400G Telluride DSPs (MxL9354x) are currently the only PAM4
DSP SoCs that successfully integrate this clocking requirement.

MaxLinear has engineered a very high-performance DSP engine in both the
transmit and receive data paths. The resulting superior link-margin
enables single-lane 100Gbps optical wavelength technology by mitigating
many of the limitations of mass production optical components.

The devices feature a comprehensive digital pre-distortion (DPD) engine
in the transmit direction to compensate for laser non-linearity and to
cancel packaging limitations that cause reflections and bandwidth
degradation at these extremely high signal frequencies. On the receive
path, the DSP includes an auto-adaptive signal enhancement engine, which
integrates a continuous time linear equalizer (CTLE), automatic gain
control (AGC), a feed forward equalizer (FFE), and a decision feedback
equalizer (DFE).
