Gigabit LAN

The PS3 has 1 Gigabit Ethernet port. The port accepts Auto-MDIX (automatic medium-dependent interface crossover), so no need for special crosscables when hooking up the PS3 direct to the PC.

Gigabit LAN chips used

A sample of the GbLAN chips in different PS3 models:

Type Size Speed Voltage Packaging Manufacturer Serial Number Description
- - - - - Marvell 88E6108-LAR1 Used in earlier models
- - - - - Marvell Alaska 88E111R Used in Slim models


Marvell 88E6108-LAR1 (IC3503)

144-TQFP
Marvell 88E6108-LAR1

Datasheet: (not available)

productcode meaning:
88E6108-LAR1

Type: Ethernet
Speed : 1Gbps
Ports : 8
Package : 144-TQFP

(sorry, no explaination yet)

The Marvell 88E6108-LAR1 is sort of a switching hub chip, with several ports that can be used in different configurations:

Port 0 (usuable as MDI 4 dif.pair) : unused (tied to ground)
Port 1 (usuable as MDI 4 dif.pair) : unused (tied to ground)
Port 2 (usuable as MDI 4 dif.pair) : wired to external UTP connector
Port 3 (GMII): Wired to SB
Port 4 (usable as TX/RX dif.pair)(100FX): wired to Wifi
Port 5 (usable as TX/RX dif.pair): unused (tied to ground)
Port 6 (usable as TX/RX dif.pair): unused (tied to ground)
Port 7 (usable as TX/RX dif.pair): unused (tied to ground)
