Alaska® 88E1116R Technical Product Brief

Gigabit Ethernet Transceiver

OVERVIEW

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.
