MaxLinear PAM4 DSP Enables Delta to Develop 400G Optical Module for Hyperscale Data Centers

  • The highly integrated Telluride family of PAM4 DSPs offers superior
    overall performance, power, and cost in a small QSFP-DD form factor

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 that Delta, a global leader in power and
thermal management solutions, has selected MaxLinear’s Telluride PAM4
DSP to develop its next-generation 400G-DR4 optical module.

The new optical module extends Delta’s broad offering of data center
connectivity products. Delta’s proprietary single mode TOSA/ROSA design
and package technology can be extended to DR4 single lambda optical
modules. Delta’s experience in data center transceiver design and its
manufacturing capabilities enables them to meet the growing demands of
hyperscale data center customers.

MaxLinear’s MxL935xx Telluride family of SoCs are key components in the
development of high-speed mega-scale 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
MxL93542 400G PAM4 DSP allows companies like Delta to develop a 400Gbps
optical interconnect module in a compact form factor for
intra-datacenter applications with a transmission distance up to 2

“The highly integrated Telluride DSPs offer superior link-margin
performance and industry leading power consumption,” said Will
Torgerson, Vice President and General Manager of MaxLinear’s High-Speed
Interconnect Group. “We are pleased to see that these features enabled
Delta to deliver their new low power DR4 optical module. These next
generation modules will address the intensifying demands for efficient
processing of burgeoning internet traffic by enabling hyperscale data
centers to transition to 400Gbps optical interconnects.”

“We find MaxLinear to be a trust-worthy partner and after surveying the
industry for the most competitive and highly integrated solution, we
decided to adopt Telluride for our DR4 optical modules,” said Ted Kuo,
Senior Director of Optical Transceiver Products at Delta. “Telluride met
all our criteria for bringing forward a competitive solution to address
the needs of hyperscale data centers.”

Technical Details

The Telluride family of low-power, high-performance PAM4 DSP SoCs enable
400Gbps/100Gbps optical modules using a 4x100Gbps/1*100Gbps optics
interface. These SoCs are suitable for use within QSFP-DD, OSFP and COBO
module form factors. The MxL93542 400G PAM4 DSP and MxL93512 100G PAM4
DSP integrate an EA-EML driver with 1.8V PP SE swing. Additional options
are available that offer differential 800mV peak-to-peak swing for non
EA-EML-based optics.

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).

MaxLinear’s Telluride PAM4 DSP enables sub-10W, 400G optical module
solutions and will be on display at MaxLinear’s booth (6509) during the
Optical Fiber Communication Conference and Exhibition from March 5-7,
2019. For an appointment, please contact MaxLinear sales at
