The Alaska
®
88E1118R Gigabit Ethernet Transceiver is
a physical layer device containing a single Gigabit
Ethernet transceiver. The transceiver implements the
Ethernet physical layer portion of the 1000BASE-T,
100BASE-TX, and 10BASE-T standards. It is manufac-
tured using standard digital CMOS process and con-
tains all the active circuitry required to implement the
physical layer functions to transmit and receive data on
standard CAT 5 unshielded twisted pair.
The 88E1118R device supports the RGMII (Reduced
pin count GMII) for direct connection to a MAC/Switch
port.
The 88E1118R device integrates MDI interface termina-
tion resistors into the PHY. This resistor integration sim-
plifies board layout and reduces board cost by reducing
the number of external components. The new Marvell
®
calibrated resistor scheme will achieve and exceed the
accuracy requirements of the IEEE 802.3 return loss
specifications.
The 88E1118R device can run off a single 1.8V, 2.5V, or
3.3V supply. Alternatively if the regulators are not used
then the 88E1118R device can run off 1.8V and 1.2V
supply.
The 88E1118R device has two regulators to generate
all required voltages. The 88E1118R device supports
1.8V, 2.5V, and 3.3V HSTL/SSTL and 2.5V LVCMOS I/
O Standards
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.

(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 88E1118R 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 reporting accurately within one meter the dis-
•
tance to the fault.
The 88E1118R device uses advanced mixed-signal pro-
cessing to perform equalization, echo and crosstalk
