88E1111 Product Brief
Integrated 10/100/1000 Ultra Gigabit Ethernet Transceiver
OVERVIEW
FEATURES
The Alaska® Ultra 88E1111 Gigabit Ethernet Trans-
•
ceiver is a physical layer device for Ethernet
•
1000BASE-T, 100BASE-TX, and 10BASE-T applica-
tions. It is manufactured using 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.
•
The 88E1111 device incorporates the Marvell Virtual
•
Cable Tester® (VCT™) feature, which uses Time
Domain Reflectometry (TDR) technology for the remote
identification of potential cable malfunctions, thus
•
reducing equipment returns and service calls. Using
•
VCT, the Alaska 88E1111 device detects and reports
•
potential cabling issues such as pair swaps, pair polar-
ity and excessive pair skew. The device will also detect
cable opens, shorts or any impedance mismatch in the
•
cable and report accurately within one meter the dis- •
tance to the fault.
•
The 88E1111 device supports the Gigabit Media Inde-
pendent Interface (GMII), Reduced GMII (RGMII),
•
Serial Gigabit Media Independent Interface (SGMII),
•
the Ten-Bit Interface (TBI), and Reduced TBI (RTBI) for
direct connection to a MAC/Switch port.
•
The 88E1111 device 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 appli- •
cations. Additionally, the 88E1111 device may be used •
to implement 1000BASE-T Gigabit Interface Converter •
(GBIC) or Small Form Factor Pluggable (SFP) modules.
•
The 88E1111 device uses advanced mixed-signal pro- •
cessing to perform equalization, echo and crosstalk
cancellation, data recovery, and error correction at a
gigabit per second data rate. The device achieves
•
robust performance in noisy environments with very low •
power dissipation.
•
The 88E1111 device is offered in three different pack-
age options including a 117-Pin TFBGA, a 96-pin BCC •
featuring a body size of only 9 x 9 mm, and a 128 PQFP
package.
•
