MaxLinear PAM4 DSP Enables Development of 400G Optical Modules for Hyperscale Data Centers

MaxLinear, Inc. (NYSE: MXL), a provider of radio frequency (RF), analog and mixed-signal integrated circuits for the connected home, wired and wireless infrastructure, and industrial and multimarket applications, has announced that uSenlight Corporation, a key OEM developing high speed, high performance, reliable integrated optical modules for datacenter, FTTx, optical networking and CPRI/LTE applications, has selected MaxLinear´s MxL93542, Telluride PAM4 DSP, to develop its next-generation 400G-DR4 and FR4 optical modules, the company said.

The new optical modules build upon the success of uSenlight´s current product offerings of 100G QSFP28 PSM4 and 100G QSFP28 CWDM4 modules for data center connectivity. uSenlight´s experience in data center transceiver design and its manufacturing capabilities enable them to meet the growing demands of hyperscale data center customers.

MaxLinear´s MxL935xx Telluride PAM4 DSPs are key components in the development of high-speed, mega-scale data centers based on 100Gbps single lambda optical interconnects. These SOCs are the world´s first DSPs 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 uSenlight to develop a 400Gbps optical interconnect module in a compact form factor for intra-datacenter applications with a transmission distance up to 2 kilometers.

The Telluride family of low-power, high-performance PAM4 DSP SoCs enable 400Gbps optical modules using a 4x100Gbps optics interface. These SoCs are suitable for use within QSFP-DD, OSFP and COBO module form factors. The MxL93542 400G 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.
