Marvell Alaska 88E1111

Single-Port Gigabit Ethernet Transceiver

PRODUCT OVERVIEW

The Marvell

implements the Ethernet physical layer portion of the 1000BASE-T, 100BASE-TX, and 10BASE-T standards. The device is

manufactured using 0.13 micron standard digital CMOS process and contains all the active circuitry required to implement the

physical layer functions to transmit and receive data on standard CAT 5 unshielded twisted pair.

Of Marvell’s single-port GbE transceivers, the 88E1111 offers the most flexible Media Access Controller (MAC) interface options.

The 88E1111 supports the Gigabit Media Independent Interface (GMII), the Reduced GMII (RGMII), the Serial GMII (SGMII),

the Ten-Bit Interface (TBI), and the Reduced TBI (RTBI) for a direct connection to a MAC/switch port.

The 88E1111 incorporates an optional 1.25 GHz SERDES (Serializer/Deserializer). The serial interface may be connected

directly to a fiber-optic transceiver for 1000BASE-T/1000BASE-X media conversion applications. By using the 88E1111, system

manufacturers can enable their systems to interchangeably support both copper and fiber media. Additionally, the 88E1111

may be used to implement 1000BASE-T Gigabit Interface Converter (GBIC) or Small Form-Factor Pluggable (SFP) modules.

The 88E1111 offers the most advanced switching feature set including the Marvell Virtual Cable Tester

used to diagnose the attached cable plant and isolate and report cable faults within one meter of accuracy.

The 88E1111 has a low power dissipation and is offered in three different package options including a 117-pin TFBGA, a 128-

pin PQFP, and a 96-pin BCC featuring a body size of only 9mm×9mm. RoHS 6/6 compliant packages are available as well as

industrial and commercial grades.
