MaxLinear PAM4 DSPs Accelerate Data Center Connectivity

Overview

MaxLinear PAM4 DSPs enable next generation fiber-optic modules for data center and hyperscale cloud networks

Data traffic continues to grow exponentially in hyperscale cloud networks; requiring ever increasing server access and switch-to-switch interconnect speeds. Low-power, high-density optical modules that support high lane rates are needed to enable higher bandwidth.

Solution

Highly Integrated DSPs & TIAs Enable Next Generation Optical Modules

MaxLinear provides a full range of PAM4 DSPs for applications ranging from 100G to 800G, supporting 53G/lane and 106G/lane options on both the host and line side interfaces for data center connectivity.
