Introduction — Intel® 82575EB Gigabit Ethernet Controller
317679-004 Intel® 82575EB Gigabit Ethernet Controller
Revision: 2.11 Datasheet
January 2011 5
1.0 Introduction
The Intel® 82575EB Gigabit Ethernet Controller is a single, compact component with two fully
integrated Gigabit Ethernet Media Access C ontrol (MAC) and physical lay er (PHY) ports. The device uses
the PCI Express Base Specification, R ev.1.1RD.
The 82575EB provides a standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and
10BASE-T applications (802.3z, 802.3u, and 802.3ab). Ports also contain a Serializer-Deserializer
(SERDES) to support 1000Base-SX/LX (optical fiber) and Gigabit backplane applications. In addition to
managing MAC and PHY Ethernet layer functions, the controller manages PCI Express packet traffic
across its transaction, link, and physical/logical layers. The SERDES can be used in SGMII mode to
connect to external PHY, either on-board or via the SFP connector.
The Intel 82575EB’s on-board System Management Bus (SMB) ports enable network manageability
implementations required by information technology personnel for remote control and alerting vi a the
LAN. With SMB, management packets can be routed to or from a management processor. Enhanced
pass-through capabilities also allow system remote control over standardized interfaces. Also included
is a new manageability interface, NC-SI that supports the DMTF preOS sideband protocol. An internal
management interface called MDIO enables the MAC (and software) to monitor and control the PHY.
Both ports support the Wake on LAN feature.
The 82575EB with PCI Express architecture is designed for high performance and low memory latency.
The device is optimized to connect to a system Memory Control Hub (MCH) using four PCI Express
lanes. Alternatively, the 82575EB can connect to an I/O Control Hub that has a PCI Express interface.
Wide internal data paths eliminate performance bottlenecks by efficiently handling large address and
data words. Combining a parallel and pipe-lined logic architecture optimized for Gigabit Ethernet and
independent transmit and receive queues, the 82575EB efficiently handles packets with minimum
latency. The 82575EB includes advanced interrupt handling features, including MSI-X support. The
82575EB uses efficient ring buffer descriptor data structures, with up to 64 packet descriptors cached
on chip. A large 48 KByte per port on-chip packet buffer maintains superior performance. In addition,
using hardware acceler ation, the controller offloads tasks from the host, such as T CP/UDP/IP checksum
calculations and TCP segmentation.
The 82575EB operation can be configured using EEPROM and FLASH; it can be also be used in EEPROM-
less configurations.
The 82575EB is packaged in a 25mm X 25mm, 576-pin flip chip ball grid array (FCBGA).

AI SERDES Receive Pairs A and B
These signals make the differential receive pair for the 1.25 GHz seria l interface. For
serializer/deserializer operation, the inputs should be coupled to ECL voltage levels. If the
SERDES interface is not used, these pins should not be connected.
SRDSO_0_P
SRDSO_0_N
SRDSO_1_P
SRDSO_1_N
AO SERDES Transmit Pairs A and B
These signals make the differential transmit pair for the 1.25 GHz serial interface. For
serializer/deserializer operation, the outputs drive the LVPECL voltage levels. If the SERDES
interface is not used, thes e pins should not be connected.
SRDS0_SIG_DET/
SRDS1_SIG_DET I Signal Detects A and B
These pins indicate whether the SERDES signals (connected to the 1.25 GHz serial interface)
have been detected by the optical transceivers. If the SERDES interface is not used with
copper media, these can be left with no connection (NC). If the SERDES interface is not used
with fiber media, the SIG_DET inputs should be tied high to VCC.
SER_RCO MP A SERDES Impedance Compensation. Connect the recommended resistor (1.4K from this
ball to ground.
SFP0_I2C_CLK O Port 0 SFP I2C clock. Connects to Mod-Def1 input of SFP. Can also be used as MDC pin.
SFP0_I2C_DATA TS/

SFP1_I2C_CLK O Port 1 SFP I2C clock. Conne c ts to Mod-Def1 input of SFP. Can also be used as MDC pin.
SFP1_I2C_DATA TS/

Table 6. Power Supply Sequencing
Figure 2. Voltage Power Sequencing Options
To meet the 375 mA inrush current requirements (not including external capacitors) the ramp time
should be 5 ms -100 ms on all power rails. For faster ramps (100 us - 5 ms), expect higher inrush
current due to the high charging current of the decoupling capacitors of 3.3 V, 1.8 V and 1.0 V rails.
5.3 Thermal Information
The 82575EB device is specified for operation when the ambient temper ature (T A) is within the r ange of
0 °C to 55 °C. For information ab out the thermal characteristics of the device, including operation
outside this range, please refer to the 82575EB Thermal Application Note.

6.2 Resets
Power-on Reset (internal): The 82575EB has an internal mechanism for sensing the power pins.
Once the power is up and stable, it creates an internal reset, this reset acts as a master reset of the
entire chip. It is level sensitive, and while it is 0, will hold all of the registers in reset. Power-on Reset
is interpreted to be an indication that device power supplies are all stable. Power-on Reset changes
state during system power-up.
In-band PCIe Reset: The 82575EB will generate an internal reset in response to a physical layer
message from the PCIe or when the PCIe link halts (entry to Polling or Detect state). This reset is
equivalent to PCI reset in previous (PCI) gigabit LAN controllers.
Main_Power_Good: Used by the device to detect the D3Cold condition and activate part of the power
saving scheme.

8.0 LED Configuration
The 82575EB provides 4 LEDs per port that may be used to indicate the status of the traffic. The
default setup of the LEDs is done via the EEPROM words 1Ch and 1Fh. The default setup for both ports
is the same. This setup is reflected in the LEDCTL register of each port. Each driver may change its
setup individually. For each of the LEDs the following parameters can be defined:
1. Mode: Defines which information is reflected by this LED. The encoding is described in the LEDCTL
register.
2. Polarity: Defines the polarity of the LED.
3. Blink mode: should the LED blink or be stable.
In addition, the blink rate of all LEDs can be defined. The possible rates are 200 ms or 83 ms for each
phase. There is one rate for all LEDs
