Marvell Alaska 88E1000 Gigabit Ethernet Transceiver

Serial EEPROM

2-4
Note: Based on current errata to the Intel 82543GC Gigabit Ethernet
Controller Datasheet/Developer's Manual (OR-2403), the 82543GC
Ethernet controller:
Requires that auto-negotiation be enabled for 1000 Mb/s
operation
Can operate at 1000 Mb/s only in full-duplex mode
The Marvell Alaska 88E100 Gigabit Ethernet Transceiver is the PMC's
physical layer device. This integrated physical device supports 10BaseT,
100BaseT, and 1000BaseT applications with power dissipation lower than
2W. The device supports IEEE 802.3 compliant interfaces GMII and MII
and supports IEEE 802.3u and 802.3ab auto-negotiation with next-page
support. Together, the device's digital signal processor (DSP) architecture,
mixed-signal processing, and digital design technology support features
such as digital adaptive equalization, echo and cross-talk cancellation, and
data recovery and error correction at a gigabit per second data rate.
For more information, see the product brief on the Marvell web site
(http://www.marvell.com).
A 1 KB serial EEPROM stores the PMC's Ethernet address and other
configuration information. The Intel 82543GC Ethernet LAN Controller
and its device driver use this information. The device driver for the
controller gains access to the EEPROM through the control/status register
(CSR). Routines are available for reading from and writing to the
EEPROM.
For more information on the contents of the EEPROM, see the
PMC/Gigabit Ethernet/82543 Driver Development Information. For more
information on the Intel 82543GC Ethernet LAN Controller's read and
write routines, see the Intel 82543GC Gigabit Ethernet Controller
Datasheet/Developer's Manual (OR-2403).
