Intel^® 82575EB Gigabit Ethernet Controller — Additional Device Features
2.6 Additional Device Features
Features
Two complete Gigabit Ethernet connections in a single device
Integrated SERDES
Four activity and link indication outputs (per port) that directly
drive LEDs
Programmable LED functionality
Internal PLL for clock generation can use a 25 MHz crystal
JTAG (IEEE 1149.1) Test Access Port built in silicon
Four software definable pins per port
Provides loopback capabilities
Four-wire SPI EEPROM interface
Benefits
• Inherent dual port teaming ability
• High availability using one port for failover
• Higher throughput than single Gigabit Ethernet port
• Lower latency due to one electrical load on the bus
• Saves critical board space
• Reduced multi-port Gigabit Ethernet costs
• Supports backplane and fiber applications as well as
copper-based Gigabit via the SGMII interface
• Link and activity indications (10, 100, and 1000 Mbps) on
each port
• Software definable function (speed, link, and activity) and
blinking allowing flexible LED implementations
• Lower component count and system cost
• Simplified testing using boundary scan
• Supports the IDCODE instruction
• Additional flexibility for LEDs or other low speed
I/O devices
• Validates silicon integrity
• Standard
2.7 Technology Features
Features
576-pin Flip-Chip Ball Grid Array (FC-BGA) package
Operating temperature:
1000BASE-T, 0 °C to 55 °C*
1000BASE-SX/LX (or SERDES backplane), 0 °C to 70 °C
Storage temperature 65 °C to 140 °C
Typical targeted power dissipation:
2.43 W @ D0 1000 Mbps
0.79 W @ D3cold 100 Mbps (wakeup enabled)
0.29 W @ D3cold (wakeup disabled)
Maxmum Payload Size: 128 and 256
Max number of transactions (TLP) supported on PCIe: Four TX DMA requests
+ 1 TX descriptor + 1 RX descriptor.
Benefits
• 25 mm X 25 mm
• Simple thermal design
• C11o5nd_°itCions: FF materials, nominal voltage,
• Minimizes impact of incorporating Gigabit
instead of Fast Ethernet.
