Gigabit Ethernet Transceiver

The Alaska
®
88E1116R 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 manu-
factured 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 88E1116R device supports the RGMII (Reduced
pin count GMII) for direct connection to a MAC/Switch
port.
The 88E1116R device integrates MDI interface termi-
nation resistors into the PHY. This resistor integration
simplifies 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 88E1116R device can run off a single 1.8V, 2.5V,
or 3.3V supply. Alternatively if the regulators are not
used then the 88E1116R device can run off 1.8V
and1.2V supply.
The 88E1116R device has two regulators to generate
all required voltages. The 88E1116R device supports
1.8V, 2.5V, and 3.3V HSTL/SSTL and 2.5V LVCMOS I/
O Standards
The 88E1116R device incorporates the Marvell® Vir-
tual 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 88E1116R device detects and
reports potential cabling issues such as pair swaps,
pair polarity and excessive pair skew. The device will
also detect cable opens, shorts or any impedance mis-
match in the cable and reporting accurately within one
meter the distance to the fault.
The 88E1116R device uses advanced mixed-signal
processing 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.
