Marvell Alaska 88E1116R

Single-Port Gigabit Ethernet Transceiver with Integrated Passives

PRODUCT OVERVIEW
The Marvell Alaska 88E1116R is a physical layer device containing a single Gigabit Ethernet (GbE) transceiver, and is the
smallest single-port GbE PHY with integrated passives. The transceiver implements the Ethernet physical layer portion of the
1000BASE-T, 100BASE-TX, and 10BASE-T standards. Manufactured using a standard digital CMOS process, the 88E1116R
contains all active circuitry required to implement the physical layer functions to transmit and receive data on standard
CAT 5 unshielded twisted-pair cable.
The Alaska 88E1116R supports the Reduced Gigabit Media Independent Interface (RGMII) for direct connection to a Media Access
Controller (MAC)/switch port. In addition, the 88E1116R 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.
The 88E1116R incorporates the Marvell Virtual Cable Tester (VCTTM) feature, which uses Time Domain Reflectometry (TDR)
for the remote identification of potential cable malfunctions, thus reducing equipment returns and service calls. With VCT
the 88E1116R detects and reports potential cabling issues such as pair swaps, pair polarity, and excessive pair skew. The device
also detects cable opens, shorts, or any impedance mismatch in the cable, and can accurately report within one meter the
distance to the fault.
The 88E1116R device integrates MDI interface termination resistors into the PHY. This resistor integration facilitates board
layout and reduces board cost by eliminating the need for twelve external passive components. The new Marvell calibrated
resistor scheme will achieve and exceed the accuracy requirements of the IEEE 802.3 return loss specifications.
The 88E1116R features two regulators to generate all required voltages, and can run off a single 1.8V, 2.5V, or 3.3V supply.
Alternatively if the regulators are not used then the 88E1116R can run off a 1.8V and 1.2V supply.

APPLICATIONS

The Alaska 88E1116R is Marvell's lowest power, single-port Gigabit Ethernet transceiver. Offered in a QFN64 measuring
only 99mm on each side, the 88E1116R is the smallest package footprint Gigabit Ethernet transceiver in the industry. The
88E1116R is ideal for GbE networking applications such as high-performance printers, game consoles, LAN on motherboards
(LOM), media vaults, and other multi-media applications requiring a connection over standard Cat-5 cable.
