PRODUCT OVERVIEW
Marvell® Alaska® 88E1514 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. The device supports SGMII/Fiber to Copper.
In addition to supporting Energy Efficient Ethernet (EEE) on the new generation of enabled MACs, this
products is 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. This
new Marvell calibrated resistor scheme will achieve and exceed the accuracy requirements of the IEEE
802.3 return loss specifications.
The 88E1514 device has an integrated switching voltage regulator to generate all required voltages and
can run off a single 3.3V supply; the device supports 1.8V, 2.5V, and 3.3V LVCMOS I/O Standards. 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 88E1514 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.
