BCM5719-4PBLK - Quad-Port 1GbE PCIe Ethernet | Broadcom
料号： BCM5719-4PBLK ✓ 量产中BCM5719-4PBLK 概述
An Ethernet controller is an interface integrated circuit that connects a host system to physical network media. The BCM5719 belongs to the Broadcom NetXtreme family and combines four 10/100/1000 Mb/s Ethernet ports with PCIe connectivity, physical-layer interfaces, packet handling, and host-facing register logic. Its quad-port architecture reduces the number of network interfaces required in a multi-gigabit server or embedded network appliance.
The controller supports connection rates of 10 Mb/s, 100 Mb/s, and 1000 Mb/s per port and complies with IEEE 802.3ab over Category 5 twisted-pair cabling. The x4 PCIe 2.1 host interface provides four lanes for system communication. These capabilities allow one controller to serve bandwidth-intensive traffic while retaining support for lower-rate legacy networks during migration or mixed-speed deployments.
BCM5719-4P is designed for systems requiring robust copper Ethernet connectivity without separate physical-layer transceiver arrangements for every port. Integrated multiport support can simplify board routing and controller software configuration compared with four independent Ethernet interface devices. Exact external PHY topology, supported media types, package dimensions, and thermal limits must be confirmed from the manufacturer data sheet and board design documentation before layout release.
Typical applications include rack-mounted servers, converged network appliances, storage systems, industrial controllers, and communications equipment. In each case, the controller can support four independently connected 1GbE links while presenting a compact x4 PCIe interface to the host processor. Administrators can use the resulting ports for management traffic, storage networking, virtual-machine connectivity, or segmented production and service networks.
A key design consideration is that controller selection depends on the complete motherboard ecosystem rather than network speed alone. Confirm the supported operating systems, firmware image, driver package, PCIe lane routing, physical-layer magnetics, connector arrangement, power budget, and thermal environment. For server integration, validate the BCM5719-compatible hardware, management firmware, and driver versions together before deployment.
This product overview consolidates the verified controller capabilities, search-intent guidance, and system-level integration considerations into one engineering reference. It also distinguishes documented facts from package, pinout, lifecycle, and replacement details that require confirmation from Broadcom before a new board or server design is released.

典型应用
BCM5719-4PBLK 适用于 6 应用s: Quad-Port Rack Server Networking, Network Storage Appliance, Industrial Ethernet Gateway, Virtualization Host, Converged Network Appliance, Communications and Edge Gateway.
Quad-Port Rack Server Networking
The BCM5719-4PBLK fits rack-server designs that need four 10/100/1000 Mb/s copper links from one controller. Its quad-port architecture can support management traffic, storage access, virtual-machine networking, or a segmented service network while preserving an x4 PCIe 2.1 connection to the host. According to the Broadcom BCM5719-4P data sheet, the controller supports IEEE 802.3ab over Category 5 twisted-pair cable. Integration still requires validated magnetics, connectors, option-ROM or firmware, and a platform-supported driver configuration.
推荐
Network Storage Appliance
A network storage appliance can use the BCM5719-4PBLK to provide four simultaneous Gigabit Ethernet service paths for storage clients, management, replication, and backup. The controller's four 10/100/1000 Mb/s ports and x4 PCIe 2.1 interface allow a system architect to consolidate connectivity without four separate Ethernet controllers. Performance evaluation should include host throughput, protocol offload configuration, latency, packet loss, and the exact driver and firmware used by the appliance.
推荐
Industrial Ethernet Gateway
The BCM5719-4PBLK is appropriate for industrial gateways that aggregate several copper Ethernet networks before forwarding traffic to a control computer or communications backplane. Its documented four-port capability supports separation of plant equipment, supervisory traffic, and external connectivity, while the 10/100/1000 Mb/s rates accommodate legacy and Gigabit devices. The selected controller ordering code must satisfy the appliance's temperature, electromagnetic, environmental, and long-term supply requirements.
推荐
Virtualization Host
Virtualization hosts can use the BCM5719-4PBLK when a platform requires four dedicated Gigabit Ethernet connections for virtual-machine networks, storage traffic, live migration, or management isolation. The x4 PCIe 2.1 host interface and four 10/100/1000 Mb/s Ethernet channels provide a consolidated hardware option. Before deployment, confirm passthrough or virtual-function support, operating-system drivers, virtualization platform certification, and whether the server platform supports the selected BCM5719 hardware and firmware combination.
推荐
Converged Network Appliance
The BCM5719-4PBLK supports converged appliances that combine multiple Ethernet services behind a single host interface. Four copper ports at 10/100/1000 Mb/s can serve internal devices, external clients, management traffic, and WAN or uplink duties when the platform assigns each function appropriately. The Broadcom BCM5719-4P data sheet confirms the quad-port PCIe 2.1 architecture, while board-level validation must address thermal performance, connectivity, driver behavior, and firmware management.
推荐
Communications and Edge Gateway
Edge and communications gateways benefit from the BCM5719-4PBLK when several copper links must terminate close to a host processor. The controller can bridge operational networks, maintenance networks, and external connectivity through four 10/100/1000 Mb/s ports over an x4 PCIe 2.1 link. System qualification should cover the exact Broadcom ordering code, supported operating temperature, electromagnetic behavior, long-term component availability, cybersecurity features, and the platform's approved driver and firmware releases.

设计说明
Use the Broadcom BCM5719-4P data sheet pin-description table and package drawing to assign the PCB netlist. Place each Ethernet channel's differential pairs according to the specified pair geometry, impedance, isolation, and connector or magnetics interface. Do not infer BCM5719-4PBLK pad assignments from another NetXtreme controller, because the verified references do not establish whether the BLK suffix changes the physical package.
Plan the x4 PCIe 2.1 interface and the four Ethernet channels as separate high-speed routing regions. Maintain continuous reference planes, avoid crossing split planes, and apply the platform's PCIe and Ethernet impedance rules consistently. Keep switching or digital circuitry away from sensitive differential pairs, and follow the manufacturer's recommended connector, magnetics, and decoupling arrangements when those details are available in the final hardware documentation.
Do not assume that any four-port Gigabit Ethernet controller is a drop-in replacement. The BCM5719-4PBLK must match the board's package, pin functions, PCIe interface, PHY requirements, clocking, supply rails, boot behavior, firmware, and driver. A different controller family can use the same Ethernet speed while requiring a different footprint, boot mechanism, or software stack. Confirm every interface before approving a substitution.
Determine the complete system power budget after selecting the final package and ordering code. The available references confirm the functional controller description but do not establish operating voltage, active power, or thermal resistance. Validate those values in the manufacturer data sheet, then check worst-case port activity, ambient temperature, airflow, and neighboring heat sources before releasing the power supply and enclosure design.
合规信息
No specific environmental or product compliance declarations are identified for the exact BCM5719-4PBLK ordering code in the verified references. Confirm RoHS, REACH, lead-free, halogen-free, conflict-minerals, and automotive qualification status with Broadcom before procurement.
