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

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-datacenter 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 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 hyper-scale 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).
