Building upon the success of the widely deployed Broadcom NIC architecture, the BCM57608 series Ethernet controllers continue to drive innovation by supporting 400Gb/s aggregate throughput while maintaining the industry’s lowest power and best thermal solution. The BCM57608 supports network interfaces of 400/200/100/50/25GbE.

Incorporating industry-leading PHY technology, the BCM57608 provides highly efficient network connectivity using eight lanes of built-in SerDes,
each supporting 100/50G PAM-4 and 10/25G NRZ. When paired with the Broadcom market-leading Strata XGS or Strata DNX Ethernet switches,
the BCM57608 ensures the highest level of performance, interoperability, and features. This includes the longest reach for passive direct attached
cables (DAC) of up to 5 meters, to accommodate most in-rack and rack to-rack deployments.

The BCM57608 supports the fourth generation, standards-based RDMA over converged Ethernet (RoCE) with hardware-based congestion
control. Broadcom RoCE congestion control not only delivers the lowest latency in real-life scenarios, but also dramatically reduces the complexity of RoCE deployment at scale.

The BCM57608 fourth-generation 400G True Flow engine integrates hardware acceleration with enhanced programmability for the parser/ lookup/match/action engine to allow for rapid implementation of new Flow types. True Flow increases virtual machine density and improves
application performance.

The BCM57608 supports technology-leading security, enabling the industry’s most secure server platform with Broadcom HW secure boot
(ROT) and attestation support.
