BCM56962B1KFSBG

BCM56962B1KFSBG is a Broadcom switch ASIC (Tomahawk-class) used in data-center switch platforms. It provides high-throughput, low-latency packet forwarding with full L2/L3 capabilities, QoS, ACLs, multicast support, and hardware acceleration for routing/processing tasks. The silicon targets high port-density configurations (typical 100 GbE/40 GbE line-rate interfaces) and is designed to be used with Broadcom software stacks (SDK/OpenNSL-style tooling) on OEM platforms. The suffix B1KFSBG denotes a specific packaging/variant of the BCM56962 silicon (temperature range, memory map, package type). For exact specifications (throughput, port counts, memory/buffer, timing), consult the official Broadcom data sheet and platform hardware guide.

I don’t have the exact official spec sheet on hand. Here’s a concise, high-level feature overview for BCM56962B1KFSBG (Tomahawk-class switch ASIC):
- High-performance L2/L3 switching with line-rate forwarding
- Supports multiple port speeds and dense port configurations (10G/25G/40G/100G)
- Hardware-based ACLs with large forwarding/TCAM for IPv4/IPv6 and multicast
- Advanced QoS with hierarchical scheduling, shaping, and policers
- VRF, ECMP routing, and IP routing support
- EVPN/VXLAN data-center fabric capabilities; MLAG support
- Precision time protocol (PTP) hardware timestamping for synchronization
- Programmable/SDK-enabled forwarding pipeline with memory/TCAM resources
- Power- and resource-efficient design suitable for data-center deployments
