MaxLinear’s Telluride PAM4 SoC Selected by ColorChip for Single-Lambda PAM4 Optical Modules

  • ColorChip’s new transceiver modules will be on display during OFC
    at MaxLinear’s booth 6509

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 ColorChip, a global leader in photonic
integrated transceivers, has selected MaxLinear’s Telluride (MxL935xx)
pulse-amplitude-modulation (PAM4) digital signal processing (DSP)
systems-on-chip (SoCs) for their next generation 400G-DR4 and 100G-DR1
optical modules.

The new optical modules join ColorChip’s multi-generational optical
engine platforms, based on proprietary SystemOnGlass™ technology.
ColorChip’s multi-generational optical engine platform has been refined
over several generations of transceivers and can truly cater to the
pressing challenges of massive data flows worldwide. ColorChip’s PAM4
100G and 400G optical interconnects based on MaxLinear’s Telluride
family are expected to be commercially available later this year.

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
MxL935xx allows companies like ColorChip to develop a 100/400Gbps
optical interconnect module in a compact form factor for
intra-datacenter applications with a transmission distance up to 2

“We are excited to see the adoption of our Telluride product family by
ColorChip for their 100Gbps QSFP28 and 400Gbps QSFP-DD transceiver
modules,” said Will Torgerson, Vice President and General Manager of
MaxLinear’s High-Speed Interconnect Group. “We look forward to working
closely with ColorChip to take these designs to production later this
year and help address rapidly increasing data loads driving the
hyperscale datacenters of the future.”

“As the industry transitions to Single Lambda PAM4 based optical
solutions, MaxLinear’s highly integrated, high-performance PAM4 DSP SoCs
along with our ground-breaking uncooled and power efficient EML-based
optical engines enabled us to develop our 100G and 400G optical
interconnect modules,” commented Eli Arad, VP R&D of ColorChip. “We are
excited to partner with MaxLinear to support the immense and
ever-evolving mega-datacenter connectivity demands through a
cutting-edge family of high-speed optical transceivers.”

Technical Details

The Telluride family feature 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).

MaxLinear’s Telluride family and ColorChip’s new optical interconnect
modules 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
