Marvell Alaska 88E1543
Quad Port 10/100/1000 Mbps Energy Efficient Ethernet Transceiver
PRODUCT OVERVIEW
Marvell

88E1543 Gigabit Ethernet Transceiver is a physical layer device containing four independent Gigabit
Ethernet transceivers. Each transceiver performs all the physical layer functions for 1000BASE-T, 100BASE-TX and
10BASE-T standards.
The device supports Quad Serial Gigabit Media Independent Interface (SGMII) to Copper and Dual-port SGMII (system)
to Copper/Fiber/SGMII with Auto-Media Detect.
In addition to supporting Energy Efficient Ethernet (EEE) on the new generation of enabled MACs, these products are
also capable of implementing EEE with legacy or non-EEE devices by incorporating EEE buffering. 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.
The Alaska 88E1543 device has an integrated switching voltage regulator to generate all required voltages and can
run off of a single 3.3V supply. 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 device achieves robust
performance in noisy environments with very low power dissipation.
The Marvell 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.
