MARVELL 88E1340SA0-BAM2I000 Gigabit Ethernet PHY Transceiver Datasheet Overview

The MARVELL 88E1340SA0-BAM2I000 is a highly integrated, single-port Gigabit Ethernet PHY transceiver designed to deliver robust performance and advanced power management for a variety of networking applications. Manufactured on an advanced process technology, this device supports 10/100/1000 Mbps operation over standard twisted-pair copper cabling, complying with the IEEE 802.3ab standard. It serves as a critical interface between the physical layer and the MAC layer in network equipment, including switches, routers, network interface cards, and industrial systems.

A key feature of this transceiver is its low power consumption, achieved through advanced power-saving technologies like Energy Efficient Ethernet (EEE) as defined in IEEE 802.3az. This allows the device to significantly reduce power usage during periods of low data activity, making it ideal for energy-conscious designs. Furthermore, it supports automotive-grade temperature ranges, enhancing its suitability for industrial and automotive networking applications where reliability under harsh conditions is paramount.

The 88E1340SA0-BAM2I000 incorporates DSP-based echo and crosstalk cancellation, enabling high-quality signal integrity and extended reach over CAT 5e and CAT 6 cables. It also features automatic MDI/MDIX crossover and polarity correction, simplifying installation and eliminating the need for crossover cables. The device offers a flexible interface to the MAC layer, typically through RGMII (Reduced Gigabit Media Independent Interface), ensuring broad compatibility with a wide range of switch and controller chips.

Comprehensive diagnostic capabilities are embedded, including cable diagnostics that can pinpoint faults like opens and shorts. This, combined with robust management interfaces such as SMI (Serial Management Interface) for register access, provides system designers with powerful tools for monitoring link status and troubleshooting.
