88E1543-A1-LKJ2C000 Marvell

The Marvell 88E1543-A1-LKJ2C000 is an Ethernet single chip with four ports that supports 10 Mbps, 100 Mbps, and 1000 Mbps. It is composed of a 128-pin Low-Power Quad Flat-Pack (LQFP) EP RoHS-compliant package. It includes an Ethernet Media Access Controller (MAC) and a single Physical Layer (PHY). The integrated 10/100/1000 Mbps Ethernet MAC supports both full-duplex and half-duplex operations on all four ports. It provides support for the IEEE 802.3, 802.3u, and 802.3ab protocols. It has a low-power, highly integrated design. Moreover, this chip provides integrated features such as Automatic Polarity Detection and Correction (Auto MDI/MDIX) and Dynamic Cable Length Detection and Compensation (Cable Equalization). Additionally, it includes two dual-speed Media Independent Interfaces (MIIs). There are also a number of operating modes available to maximize system energy savings. This chip is ideal for use in next-generation Digital Subscriber Lines (DSLs) and residential gateways.
