BCM57414B1KFSBG

Overview

The BCM57414B1KFSBG is a dual-port 25 Gb/s Ethernet MAC controller manufactured by Broadcom Limited. It integrates a dual-channel 25 Gb/s SFI transceiver and supports PCIe 3.0 x8 interface at Gen3 x8 speed. The component enables network speeds of 25 Gb/s, 10 Gb/s, and 1 Gb/s per port. Key technical features include transmit-side scaling (TSS), VLAN insertion/removal, interrupt coalescing, and support for Wake-on-LAN (WOL). It also provides network boot capabilities via PXE and UEFI, iSCSI boot support, and MSI/MSI-X interrupt handling.

Feature Summary

• Dual-port 25 Gb/s Ethernet connectivity with integrated SFI transceiver
• PCIe 3.0 x8 interface compatibility for high-speed data transfer
• Support for multiple link speeds including 25 Gb/s, 10 Gb/s, and 1 Gb/s
• Hardware acceleration for TSS, VLAN processing, and interrupt coalescing

Applications

• Dual-port 25-Gigabit Ethernet adapters for OCP systems
• Server networking solutions requiring high throughput
• Data center infrastructure utilizing SFP28 optical modules or copper direct-attach cables

Procurement Notes
