Marvell Alaska 88E1510/88E1518
Integrated 10/100/1000 Mbps Energy Efficient Ethernet Transceivers
PRODUCT OVERVIEW
Marvell^® Alaska^® 88E1510 and 88E1518 Gigabit Ethernet (GbE) transceiver are physical layer devices each containing a
single Gigabit Ethernet transceiver. The transceivers implement the Ethernet physical layer portion of the 1000BASE-T,
100BASE-TX, and 10BASE-T standards.
The devices also integrate 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 88E1510 and 88E1518 devices have an integrated switching voltage regulator to generate all required voltages
and can run off a single 3.3V supply with the 88E1510 supporting 2.5V/3.3V LVCMOS I/O Standards and the
88E1518 supporting only 1.8V LVCMOS I/O Standard. This devices use advanced mixed-signal processing to perform
equalization, echo and crosstalk cancellation, data recovery, and error correction at a gigabit per second data rate. The
devices achieve 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.
