➀ The development of 448G SerDes is critical for scaling Ethernet beyond 1.6T, supporting AI/data center infrastructures through advanced modulation schemes like PAM4/PAM6.

➁ Industry standards bodies (OIF, IEEE, SNIA) are collaborating on specifications, while Synopsys accelerates PHY development via channel topology analysis and DSP architecture modeling.

➂ Key technical challenges include managing symbol transition complexity and balancing power/performance trade-offs in 448G SerDes implementations.

➀ Samtec showcased its Si-Fly® HD 224 Gbps PAM4 interconnect technology at DesignCon, collaborating with Broadcom.

➁ The demo featured Broadcom’s 200 Gbps SerDes technology and Samtec’s high-speed cable systems.

➂ The collaboration aims to enhance system performance and open new horizons in multi-channel SerDes technology.
