MaxLinear’s 2nd Generation PAM4 DSP Selected by Centera Photonics to Deliver Sub-3.5W 100G Optical Modules for Hyperscale Data Centers

▤ Summary

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 Centera Photonics Inc., a silicon photonics optical solution provider for high performance interconnects, has selected MaxLinear’s Telluride PAM4 DSP (MxL93516) for their next generation 100G-DR1 optical modules. Like the first-generation Telluride DSPs, the new device offers a monolithically integrated EA-EML laser driver that significantly reduces the overall optical module BOM cost. The MxL93516 allows companies like Centera to develop a 100Gbps optical interconnect module in a compact form factor for intra-datacenter applications with a transmission distance up to 2 kilometers. By using MaxLinear’s MxL93516 we developed a single-lambda PAM4 DSP-based module that requires fewer electrical and optical components, lowering our costs, improving our yields, and increasing module reliability,” said Dr. Brian Lan, R&D Director at Centera Photonics Inc. “The MxL93516 PAM4 DSP has enabled us to develop single-lambda 100G optical transceivers that address broader market segments requiring sub-3.5W modules.” Technical Details The MxL93516 is part of MaxLinear’s second-generation Telluride family of low-power, high-performance PAM4 DSP SoCs. The MxL93515 and MxL93516 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.
