博通推出支持200Gbps接口的DSP PHYBroadcom DSP PHY supports 200Gbps interfaces
➀ 博通宣布其200Gbps每通道PAM-4 DSP PHY Sian2的通用可用性，该产品支持100Gbps电接口和200Gbps光接口。Sian2和Sian DSP旨在支持下一代AI集群所需的200G/通道接口模块。➁ 为了实现更高的带宽、更低的功耗、更低的延迟和更低的成本，需要从目前AI集群中使用的400G/800G链路（100G/通道光模块）迁移到800G/1.6T链路（200G/通道光模块）。➂ Sian2和Sian DSP针对800G和1.6T光模块平台进行了优化，通过降低功耗、延迟和每比特成本，实现了带宽翻倍，以促进AI数据中心规模的扩大。➀ Broadcom has announced the general availability of Sian2, its 200Gbps per lane PAM-4 DSP PHY that supports 100Gbps electrical and 200Gbps optical interfaces. Sian2 and Sian DSPs are designed to enable pluggable modules with 200G/lane interfaces for next-generation AI clusters. ➁ The migration from 400G/800G links with 100G/lane optics to 800G/1.6T links with 200G/lane optics is necessary for higher bandwidth, lower power, lower latency, and lower cost. ➂ Sian2 and Sian DSPs are optimized for 800G and 1.6T optical module platforms, doubling the bandwidth with lower power, lower latency, and lower cost per bit to facilitate AI data center scale.
