MARVELL 88E8057-A0-NNC2C000 Gigabit Ethernet Controller Datasheet and Technical Specifications

The MARVELL 88E8057-A0-NNC2C000 is a highly integrated, single-port Gigabit Ethernet controller designed for high-performance networking applications. It leverages Marvell’s advanced Alaska® Gigabit Ethernet technology, offering a robust and power-efficient solution for desktop, workstation, and embedded systems. This controller supports both PCI Express® 1.0a and 1.1 interfaces, ensuring broad compatibility with modern computing platforms.

A key feature of the 88E8057 is its full compliance with the IEEE 802.3, 802.3u, and 802.3ab standards, guaranteeing interoperability in 10/100/1000 Mbps networks. It incorporates an integrated 10-bit A/D converter and a DSP-based adaptive equalizer, enabling reliable operation over CAT 5 UTP cabling with superior signal integrity and crosstalk cancellation.

The controller is built with power management in mind, supporting ACPI 2.0 compliant power states for modern energy-efficient systems. It features Wake-on-LAN (WoL) and Magic Packet® detection, allowing the host system to be awakened from a low-power state via a network command. For advanced traffic management, it includes support for Quality of Service (QoS) with IEEE 802.1p Layer 2 priority encoding and IPv4/IPv6 checksum offloading, which significantly reduces CPU overhead.

Security and manageability are enhanced through Jumbo Frame support and VLAN tagging (IEEE 802.1Q). The device is offered in a compact, 128-pin LQFP package, making it suitable for space-constrained designs. Its low-power 0.13-micron CMOS process ensures high performance with minimal thermal output.

ICGOODFIND: The Marvell 88E8057-A0-NNC2C000 stands out as a reliable, standards-compliant Gigabit Ethernet controller. Its integration of critical PHY and MAC functions into a single chip, combined with advanced power management and robust signal processing capabilities, makes it an excellent choice for designers seeking a proven and efficient networking solution.
