Marvell Alaska 88E1322
Integrated 10/100/1000 Mbps Energy Efficient Ethernet Transceivers
PRODUCT OVERVIEW
Marvell^® Alaska^® 88E1322 Gigabit Ethernet (GbE) transceiver is a physical layer device containing 2 Gigabit Ethernet
transceivers. The transceivers implement the Ethernet physical layer portion of the 1000BASE-T, 100BASE-TX, 10BASE-T,
1000BASE-X, and 100BASE-FX standards.
The device supports SGMII (Serial Gigabit Media Independent Interface for direct connection) to Copper/Fiber/100BASE-
FX and Copper/Fiber with Auto-Media Detect. The device also integrates MDI interface termination 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.
This 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 88E1322 achieves robust performance in noisy
environments with very low power dissipation.
The Alaska family of transceiver products provides the ideal solution for rapid development and deployment of gigabit
standalone and switching systems for the Enterprise, embedded, consumer, and Metro/service provider market segments.
