Overview
The BCM5720LA0KPBG is a dual-port Ethernet controller from the Broadcom NetXtreme II series, designed for server and storage networking applications. It supports 1 Gigabit Ethernet speeds over copper interfaces. The device integrates MAC functionality with an embedded processor to offload TCP/IP processing tasks, reducing host CPU utilization. It utilizes a PCI Express interface for system connectivity. The component operates within a commercial temperature range of 0°C to 70°C and is housed in a BGA package.
Feature Summary
- Dual-port architecture providing independent network connectivity on two separate physical links
- Integrated TCP/IP offload engine to reduce host processor overhead during data transmission
- Supports standard PCIe bus interface for high-speed communication with the host system
Applications
- Enterprise server network interface cards
- Storage area network (SAN) connectivity solutions
- Data center infrastructure equipment
Procurement Notes
Verify the specific suffix 'LA0' against official datasheets to confirm pinout compatibility and feature set. Ensure the source document explicitly identifies this part as a dual-port Gigabit Ethernet controller. Check for RoHS compliance status in the latest manufacturing documentation before integration into regulated products.
Selection Notes
Select this component when dual independent Gigabit connections are required within a single form factor. Compare power consumption metrics against single-port alternatives if thermal constraints are critical. Verify that the host system provides sufficient PCIe lanes to support the dual-port bandwidth requirements without bottlenecking.
Part Context
This part belongs to the Broadcom NetXtreme II family, which established standards for integrated Ethernet controllers in enterprise environments. It succeeded earlier generations by offering improved offloading capabilities and higher integration levels. The model represents a specific variant optimized for commercial temperature ranges and standard packaging configurations.
Replacement Considerations
Direct replacements may include other NetXtreme II variants such as the BCM5720A0KFBG, provided pin compatibility and feature sets match exactly. Verify that any substitute maintains the same dual-port configuration and PCIe interface specifications.
