Pulse Amplitude Modulation PAM4

Keysight offers complete PAM-4 solutions for simulation, input and output design characterization for 32 Gbaud and beyond.

Demand for increased network bandwidth in data centers continues to grow. Providing 400 Gb/s, also called 400G, links will be the next step in meeting the continuing need for increased network bandwidth in data centers. Multi-level signaling formats such as Pulse Amplitude Modulation (PAM-N) are technologies that will enable 400G implementation. However, the revolutionary switch from non-return-to-zero (NRZ) to PAM-4 presents many new design, measurement, and test challenges.

The resources you find here provide an overview of PAM-4 and PAM-N design, an explanation of the latest measurement techniques, and an illustration of design and debug approaches and test solutions. Work with Keysight and gain insights for your best design.
