Marvell Alaska 88E3082/88E3083
FEATURES
BENEFITS
• Eight independent IEEE 802.3 compliant 100BASE-TX and 10BASE-T ports
• PECL interface supporting 100BASE-FX applications on a per port basis
(88E3082 only; 88E3083 supports one fiber port)
• RMII, SMII, and SSSMII interfaces (RMII supported on 88E3082 only)
• Lower power dissipation, 150mW/port
• Power management modes
• Virtual Cable Tester feature
• Auto-MDI/MDIX crossover for 100BASE-TX and 10BASE-T ports
• Jumbo frame support to 10 KB with up to +/-150 ppm clock jitter
• IEEE 802.3u Auto-Negotiation support for automatic speed and duplex selection
• Far-End-Fault-Indication (FEFI) support for 100BASE-FX applications
• 100BASE-TX performance over 150 meters
• Flexible serial and parallel LED support
• IEEE 1149.1 standard test access port and boundary scan compatible
• Small outline packaging; 88E3082 in 224-pin TFBGA, 88E3083 in 128-pin LQFP
• Enable higher port density switch system design
• Supports FE over fiber applications
• Provides user configurable digital interfaces. SSSMII option extends the
distance between the PHY and SW/MAC chip on the PCB design
• Yields higher port density and lower cost
• Reduces system power
• Enables remote cable diagnostics for fault detection
• Simplifies and reduces the cost of networking installation
• Supports applications that demand larger packet sizes
• Enables a plug-and-play network system
• Improves network reliability
• Tolerates more cable mismatch and extends the receiving distance over 150
meters on standard CAT 5 cable
• Eliminates cost of external LED latches and drivers
• Allows for implementation of JTAG function facilitating board-level debugging
• Provides flexible package options for reduced PCB real estate
APPLICATIONS
The Marvell Alaska 88E3082 and 88E3083 8-port transceivers are ideal for high-port density FE routers, hubs, and switches.
The ultra-low power dissipation of only 150mw per port and the Marvell VCT advanced cable diagnostics enable the most
cost-effective designs.
