MARVELL 88E8059-A0-NNB2C000 Gigabit Ethernet Controller: Datasheet and Technical Specifications

The MARVELL 88E8059-A0-NNB2C000 is a highly integrated, single-port Gigabit Ethernet controller designed to provide robust, high-performance network connectivity for a wide range of computing applications. Fabricated using advanced CMOS technology, this controller is engineered to deliver low power consumption and high-speed data throughput, making it an ideal solution for desktop PCs, workstations, embedded systems, and network appliances.

A key architectural highlight of the 88E8059 is its PCI Express 1.1 interface, which offers a high-bandwidth, scalable connection to the system chipset. This ensures minimal latency and maximizes data transfer rates, fully leveraging the capabilities of Gigabit Ethernet. The controller integrates a high-performance Gigabit Ethernet MAC (Media Access Control) and PHY (Physical Layer transceiver) into a single chip, simplifying board design and reducing the overall bill of materials.

The integrated PHY supports auto-negotiation and crossover detection and correction (Auto-MDIX) for all operating modes (10/100/1000 Mbps), allowing for seamless connection using standard straight-through or crossover cables. For enhanced traffic management and quality of service (QoS), the device supports IEEE 802.1p Layer 2 priority encoding and IEEE 802.1Q VLAN tagging. Advanced features like TCP/IP, UDP, and checksum offloading are implemented to significantly reduce CPU overhead, improving overall system performance and efficiency.

Security and manageability are addressed through support for IEEE 802.3az Energy Efficient Ethernet (EEE), which reduces power consumption during periods of low data activity. The controller also offers Jumbo Frame support for improved large data transfer efficiency. It is designed to be compliant with leading ACPI power management specifications, enabling efficient power states for modern energy-conscious systems.

The 88E8059-A0-NNB2C000 is offered in a compact, RoHS-compliant package and is characterized for commercial temperature ranges, ensuring reliability for its target applications.
