BCM56980 Datasheet | Broadcom

Overview The Broad® BCM56980 family is a class of high-performance, high-connectivity network switching devices supporting up to 32x 400Gb E, 64x 200Gb E, or 128x 100Gb E switch ports. The device family features a maximum of 32 integrated Blackhawk Cores, each with eight integrated 50G PAM4 Ser Des transceivers and associated PCS for native support of XFI, 10GBASE-KR/CR/SR/ER/LR, 40GBASE-KR4/CR4/SR4/ER4/LR4, 50Gb E, and 100GBASE-KR4/CR4/SR4/ER4/LR4. The BCM56980 delivers high-bandwidth, glueless network connectivity up to 12.8 Tb/s on a single chip. The BCM56980 is a family of Ethernet switches designed to address performance, capacity, and service requirements for next-generation data center and cloud puting environments. The BCM56980 architecture delivers plete Layer 2 (L2) and Layer 3 (L3) switching and routing capabilities with maximum port density, while consuming minimum power, latency, and board footprint. Software patibility is maintained across the Strata XGS® product portfolio to simplify customer designs and reduce customer time-to-market. As server interfaces transition to higher Ethernet speeds and virtualization continues to increase link utilization, data center networks are demanding switches with dense 100Gb E and 400Gb E connectivity at the edge and aggregation layers. With up to 256 50G PAM4 Ser Des that conform to IEEE 802.3bs and 802.3cd specifications, and full flexibility in configuring 10/25/40/50/100/200/400Gb E ports, a single BCM56980 switching chip can be used to build scalable, cost-effective Top of Rack (To R) switch, blade switch, and aggregation equipment across the entire data center. The BCM56980 has extensive features to address the rapidly increasing scale of data center network deployments and distributed puting applications: large L2 and L3 forwarding capacity supporting numerous multi- pathing technologies; enhanced instrumentation; switching, migration, and robust buffer performance including manyto-one burst absorption capabilities...
