Introduction

Note:

Unless specifically noted, 82573 refers to the Intel® 82573E, 82573V and 82573L GbE

controllers.

82573 GbE controllers are single, compact components with integrated Gigabit

Ethernet Media Access Control (MAC) and Physical Layer (PHY) functions. These

devices use PCIe* architecture (Revision 1.0a). For desktop, workstation, and value

server network designs with critical space constraints, the 82573 enables a GbE

implementation in a very small area.

The 82573 provides a standard IEEE 802.3 Ethernet interface for 1000BASE-T,

100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab, respectively).

In addition to managing MAC and PHY Ethernet layer functions, the 82573 manages

PCIe* packet traffic across its transaction, link, and physical and logical layers.

The 82573E contains a dedicated microcontroller for manageability with an on-board

Intel^®Active Management Technology (Intel^®AMT) enabling network. This enables

manageability implementations required by information technology personnel for out-

of-band management, remote troubleshooting and recovery, asset management, and

non-volatile storage. Intel^®AMT is the first step towards a complete Intel^®Cross-

Platform Manageability Program (Intel® CPMP), which is a business and technology

initiative to deliver consistent management capabilities, protocols, and interfaces

across all Intel platforms.

The 82573E and 82573V GbE controllers have an integrated System Management Bus

(SMBus) port enabling industry standards, such as the Alert Standard Forum (ASF) 2.0.

With SMBus, management packets can be routed to or from a management processor.

In addition, integrated ASF 2.0 circuitry provides alerting and capabilities with

standardized interfaces.

The 82573 with PCIe* architecture is designed for high performance and low memory

latency. The device is optimized to connect to a system I/O Control Hub (ICH7) using

one PCIe* lane. Alternatively, the 82573 is able to connect to a Memory Control Hub

(MCH) device with a PCIe* interface.

Wide internal data paths eliminate performance bottlenecks by efficiently handling

large address and data words. The 82573 efficiently handles packets with minimum

latency by combining a parallel and pipelined logic architecture optimized for GbE and

independent transmit and receive queues. The 82573 also includes advanced interrupt

handling features and uses efficient ring buffer descriptor data structures, with up to 64

packet descriptors per queue cached on chip. A 32-KB on-chip packet buffer maintains

superior performance. In addition, using hardware acceleration, the 82573 offloads

tasks from the host (for example, TCP/UDP/IP checksum calculations and TCP

segmentation).

The 82573L features low power management. During the L1 and L2 link states, the

82573L asserts the Clock Request signal (CLKREQ#) to indicate that its PCIe*

reference clock can be gated.

The 82573 is packaged in a 15 mm X 15 mm, 196-Ball Grid Array (BGA).

PCIe* Data Signals

Signal

Type

Name and Function

PCIe Differential Reference Clock

The reference clock is furnished by the system and has a 300 ppm frequency

tolerance. It is used as reference clock for PCIe transmit and receive circuitry

and is used by the PCIe core PLL to generate 125 MHz and 250 MHz clocks for

the PCIe* core logic.

PE_CLKn

PE_CLKp

A(In)

PCIe* Serial Data Output

PE_T0n

PE_T0p

These signals connect to corresponding PERn and PERp signals on a system

motherboard or a PCIe* connector. Series AC coupling capacitors are required

at the 82573 device end. The PCIe* differential outputs are clocked at 2.5 Gb/s.

A(0ut)

A(In)

PCIe Serial Data Input

PE_R0n

PE_R0p

These signals connect to corresponding PETn and PETp signals on a system

motherboard or a PCIe* connector. The PCIe* differential inputs are clocked at

2.5 Gb/s.

2.3

PCIe* Miscellaneous Signals

Signal

PE_RST#

Type

Name and Function

Reset

I

This signal indicates whether or not the PCIe* power and clock are available.

Wake

This signal is driven to zero when it receives a wake-up packet and either the PME

enable bit of the Power Management Control/Status Register is set to 1b or the

Advanced Power Management enabled bit of the Wake Up Control Register equals

1b.

PE_WAKE#

OD

I

Auxiliary Power Present

AUX_

AUX_PRESENT must be pulled up to 3.3V standby power if the 82573 is powered

from standby supplies. This signal must be pulled down if auxiliary power is not

used.

PRESENT

(AUX_PWR)¹

Clock Request.

The Clock Request (CLKREQ#) signal is located at ball P9 of the 82573L. When it is

sampled high, this open-drain signal alerts the system that the 82573L does not

need the PCIe* differential reference clock. During normal operation, the 82573L

keeps CLKREQ# asserted (low), and the system supplies this clock to the device on

the PE_CLKp and PE_CLKn signals. The 82573L deasserts CLKREQ# (high) when it

is in an electrical idle state (L1 and L2), and the system might choose to continue

supplying the reference clock or gate it conserving platform power. The CLKREQ#

signal should be connected to the clock driver that supplies the 82573L PCIe*

clock. If other devices use the same CLKREQ# signal, a pull-up resistor should be

used to ensure that no device pulls this signal low when it is powered off.

3.3V, 2.5V, and 1.2V. This is covered in Section 3.3.1.

• Powering the 82573 with only an external 3.3V supply and using internal power

regulators from the 82573 combined with external PNP transistors to supply the

2.5V and 1.2V levels. This is covered in Section 3.3.3.

• Using the 2.5V internal (on-die) regulator combined with an external PNP transistor

to supply the 1.2V level. This is covered in Section 3.3.3.

3.3.2

Power Sequencing with External Regulators

The following power-on and power-off sequence should be applied when external power

supplies are in use. Designs must comply with the required power sequence to avoid

risk of either latch-up or forward biased internal diodes.

Generally, the 82573 power sequencing should power up the three power rails in the

following order: 3.3V Æ 2.5V Æ 1.2V. However, if this general guideline is not followed,

there are specific requirements that must be adhered to. These requirements are listed

in the following two subsections.

3.3.2.1

External LVR Power Up Sequencing and Tracking

Sequencing of the external supplies during power up might be necessary to ensure that

the 82573 is not electrically overstressed and does not latch-up. These requirements

are shown in Figure 2.

The 82573 core voltage (1.2V) cannot exceed the 3.3V supply by more than 0.5 V at

any time during the power up. The 82573 core voltage (1.2V) cannot exceed the 2.5V

supply by more than 0.5 V at any time during the power up. The core voltage is not

required to begin ramping before the 3.3V or the 2.5V supply.

The 82573 analog voltage (2.5V) can not exceed the 3.3V supply by more than 0.5 V at

any time during the power up. The analog voltage is not required to begin ramping

before the 3.3V supply.

• If the 1.2V and 2.5V rails power up before 3.3V, they should never exceed the 3.3V

supply by more than 0.3 V.

• At power down, all three supplies should be turned off simultaneously. If the 3.3V

supply powers down first, the 1.2V and 2.5V supplies must never exceed the 3.3V

supply by more than 0.3 V.

3.3.2.2

External LVR Power Down Sequencing

There are no specific power down sequencing and tracking requirements for the 82573

silicon. The risk of latch-up or electrical overstress is small since the only charge storing

in decoupling capacitors is left in the system.

3.3.3

Internally Generated Power Delivery

The 82573 has two internal linear voltage regulator controllers. The controllers use

external transistors to generate 2 of the 3 required voltages: 2.5V (nominal) and 1.2V

(nominal). These two voltages are stepped down from a 3.3V source.

3.3.4

Internal LVR Power Sequencing

All supplies should rise monotonically. Sequencing of the supplies is controlled by the

82573.

3.3.4.1

Power Up Sequencing and Tracking

During power up, the sequencing and tracking of the internally controlled supplies

(2.5V and 1.2V) are controlled by the 82573. No specific motherboard requirements

are necessary to prevent electrical overstress or latch-up.

The 82573 analog voltage (2.5V) never exceeds the 3.3V supply at any time during the

power up. This is because the 2.5V supply is generated from the 3.3V supply when the

internal voltage regulator control logic is being used. Figure 3 shows the internal LVR

circuit. The 2.5V supply tracks the 3.3V ramp.

The 82573 core voltage (1.2V) never exceeds the 3.3V at any time during the power

up. This is because the 2.5V supply is generated from the 3.3V supply when the

internal voltage regulator control logic is being used. Figure 3 shows the internal LVR

circuit. The 1.2V ramp is delayed internally to prevent it from exceeding the 2.5V and

3.3V supply at any time. The delay is proportional to the slope of the 3.3V ramp.

The delay is approximated by T_ramp(3.3V)*0.25 < T_delay(1.2V) < T_ramp(3.3V)*0.75.

T_rampis defined to the ramp rate of the 3.3V input to the internal voltage regulator

circuit.

• It is recommended that the voltage on a lower voltage rail never exceed the

voltage on a higher voltage rail during power on.

• There are no minimum time requirements between the voltage rails as long as they

power up in sequence: 3.3V → 2.5V → 1.2V.

• All 3 supplies must be stable for at least 80 ms before LAN_PWR_GOOD is

asserted. 100 ms is preferable if possible.

• A PCIe* reset must occur after LAN Power Good is active.

3.3.4.2

Internal LVR Power Down Sequencing

There are no specific power down sequencing and tracking requirements for the 82573

Internal LVR Board Schematic

When using the internal voltage regulator controllers built into the 82573, resistors

might need to be placed in series with the emitter in order to prevent the PNP

transistors from overheating. These series resistors dissipate a portion of the power

that would otherwise be dissipated by the PNP devices. The value and power rating of

the resistors must be carefully chosen to balance thermal limits against the PNP

characteristics against total current draw. The regulator must never drop below the

minimum V_ceand out of the linear region.

The effective resistance of the pass resistors should equal approximately 1 Ω and have

a combined power dissipation rating of 0.5 Watts for the 82573. Figure 4 shows the

recommended implementation.

External Clock Oscillator

If an external oscillator is used to provide a clock to the 82573, the connection shown

in the figure below must be used. The XTAL2 output signal of the 82573 must not be

connected. The XTAL1 input signal receives the output of the oscillator directly. AC

coupling is not recommended.

Package and Pinout Information

This section describes the 82573 physical characteristics and pin-to-signal mapping.

4.1

Package Information

The 82573 device is a lead-free 196-pin thin and Fine Pitch Ball Grid Array (TF-BGA)

measuring 15 mm by 15 mm. The nominal ball pitch is 1.0 mm.

Thermal Specifications

The case temperature (T_C) is calculated using the equation:

T_C= T_A+ P (⎝JA - ⎝JC)

Junction temperature (T_J) is calculated using the equation:

T_J= T_A+ P ⎝JA

The power consumption (P) is calculated by using the typical ICC and nominal VCC

where T_Arepresents the ambient temperature. The thermal resistances are listed in

Table 21.

Thermal resistances are determined empirically with test devices mounted on standard

thermal test boards. Real system designs may have different characteristics due to

board thickness, arrangement of ground planes, and proximity of other components.

The case temperature measurements should be used to assure that the 82573 is

operating under recommended conditions. The use of a heat sink device is not

required.
