The Marvell® PAM4 optical DSP portfolio addresses the critical the need for high-bandwidth optical interconnects to power AI infrastructure. Marvell leads the
The BCM56980 device family incorporates PAM4-based SerDes Core (BC). This macro allows the device to support low-latency throughput, oversubscription capability, and Flexport configuration.
Although PAM4 doubles the bit bearing efficiency compared with NRZ, PAM4 has noise, linearity, and sensitivity issues. This section focuses on test technologies at the physical layer.
56G SerDes IP core supports PAM4 signaling in the range of 25.0-60.0 Gbps using full-rate and half-rate modes with scrambled data. Non-return-to-zero (NRZ) signaling is supported in the range
🎯 Why This Matters Network architects, data-center engineers, and telecom professionals face growing bandwidth demands from AI, cloud, 5G, and hyperscale environments. The right
