intentionally left blank vi Product Datasheet 82571EB/82572EI Gigabit Ethernet Controller 1.0 Introduction The Intel 82571EB Gigabit Ethernet Controller is a single, compact component with two fully integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY) ports. The Intel 82572EI Gigabit Ethernet Controller is a single-port version of the controller in the same package. These devices use the PCI Express* architecture (Rev. 1.0a). The Intel 82571EB/82572EI enables dual- or single-port Gigabit Ethernet implementation in a very small area and can be used for server and workstation network designs with critical space constraints. The Intel 82571EB/82572EI provides a standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 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 Intel 82571EB/82572EI’s on-board System Management Bus (SMB) ports enable network manageability implementations required by information technology personnel for remote control and alerting via the LAN. With SMB, management packets can be routed to or from a management processor. The SMB ports enable industry standards, such as Alert Standard Format (ASF) 2.0, to be implemented using the 82571EB/82572EI controller. In addition, on-chip ASF 2.0 circuitry provides alerting and remote control capabilities with standardized interfaces. Enhanced passthrough capabilities also allow system remote control over standardized interfaces. The 82571EB/82572EI Gigabit Ethernet Controller 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 82571EB/82572EI controller can connect to an I/O Control Hub (ICH6 & 7) 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 82571EB/82572EI controller efficiently handles packets with minimum latency. The 82571EB/82572EI controller includes advanced interrupt handling features. The 82571EB/82572EI 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 acceleration, the controller offloads tasks from the host, such as TCP/UDP/IP checksum calculations and TCP segmentation. The 82571EB/82572EI is packaged in a 17 mm X 17 mm, 256-ball grid array. 1.1 Document Scope This document contains targeted datasheet specifications for the 82571EB/82572EI Gigabit Ethernet Controller, including signal descriptions, DC and AC parameters, packaging data, and pinout information.

Signals SRDSI_0_PLUS and SRDSI_0_MINUS make the differential receive pair for the 1.25 GHz serial interface for Port 0. For serializer/ deserializer operation, the inputs should be coupled to ECL voltage levels. Signals SRDSI_1_PLUS and SRDSI_1_MINUS make the differential receive pair for the 1.25 GHz serial interface for Port 1. 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.

Signals SRDSO_0_PLUS and SRDSO_0_MINUS make the differential transmit pair for the 1.25 GHz serial interface for Port 0. For serializer/ deserializer operation, the outputs drive the LVPECL voltage levels. Signals SRDSO_1_PLUS and SRDSO_1_MINUS make the differential transmit pair for the 1.25 GHz serial interface for Port 1. For serializer/deserializer operation, the outputs drive the LVPECL voltage levels. If the SERDES interface is not used, these pins should not be connected. Signal Detects. These pins (SRDSA_SIG_DET for Port 0; SRDSB_SIG_DET for Port 1) 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, the SIG_DET inputs can be left unconnected. SERDES Impedance Compensation. Connect the recommended resistor value across these balls, even if not using the SERDES interface. Refer to the 82571EB/82572EI Design Guide for the recommended value.

Device functionality to stated DC and AC limits is not guaranteed, if conditions exceed recommended operating conditions. b. See Section 4.2.2 for voltage ramp and sequencing recommendations. c. Operation with internal voltage regulator control of PNP pass transistor may exceed this range due to 82571EB process skew tracking. d. 1000BASE-T designs require thermal management (heatsink and/or forced air flow) to achieve 0° to 55° C operation. Increased thermal management can increase this temperature range to 0° to 70° C. Applications using the SERDES interface are rated for 0° to 70° C without thermal management. 18 Product Datasheet 82571EB/82572EI Gigabit Ethernet Controller 4.2.2 Table 3.

For faster ramps (100 us - 5 ms), expect higher inrush current due to the high charging current of the decoupling capacitors of 3.3V, 1.8V and 1.1V rails. 4.3 Table 6.
