MaxLinear launches 400Gbps PAM4 DSP SoC

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 the Telluride family (MxL935XX) of 400Gbps pulse-amplitude-modulation (PAM4) digital signal processing (DSP) systems-on-chip (SoC) solutions addressing the high-speed optical interconnect needs of mega-scale cloud and enterprise data centers, the company said.

The MxL935XX Telluride family of devices is the world´s first DSP SoCs with integrated electro-absorption modulated laser (EA-EML) drivers for 400Gbps optical interconnects. The MxL935XX device is the key component for system vendors to be able 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 MxL935XX 16nm CMOS PAM4 DSP SoC consumes an extremely low power of 6.7W, which includes the integrated EA-EML driver power dissipation. The minimal power consumption of the MxL935XX meets the stringent power constraints of 400Gbps optical module form-factors, namely QSFP-DD, OSFP and COBO devices.
