Product Brief
Overview
Marvell® Alaska® 88E1512 Gigabit Ethernet (GbE) 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 RGMII (Reduced pin count GMII for
direct connection) to Copper/Fiber/SGMII with Auto-Media Detect,
RGMII to Copper, RGMII to SGMII/Fiber, and SGMII to Copper.
The device also integrates MDI interface termination resistors
into the PHY. This resistor integration simplies 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 specications.
The 88E1512 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 mixedsignal
processing to perform equalization, echo and crosstalk
cancellation, data recovery, and error correction at a gigabit per
second data rate. The 88E1512 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.
