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 outof-band management, remote troubleshooting and recovery, asset management, and
non-volatile storage. Intel® AMT is the first step towards a complete Intel® CrossPlatform 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
2.3
Type
Name and Function
PE_CLKn
PE_CLKp
A(In)
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_T0n
PE_T0p
A(0ut)
PCIe* Serial Data Output
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.
PE_R0n
PE_R0p
A(In)
PCIe Serial Data Input
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.
PCIe* Miscellaneous Signals
Signal
Type
Name and Function
I
Reset
This signal indicates whether or not the PCIe* power and clock are available.
PE_WAKE#
OD
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.
AUX_
PRESENT
(AUX_PWR)1
I
Auxiliary Power Present
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.
OD
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.
PE_RST#
CLKREQ#
(82573L only)
1. This signal is used in all three devices and has the same functionality but is denoted as AUX_PRESENT in the
82573E/V and AUX_PWR in the 82573L.

Power Supply Connections
There are three options in providing power to the 82573:
• Connecting the 82573 to three external power supplies with nominal voltages of
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 Tramp(3.3V)*0.25 < Tdelay(1.2V) < Tramp(3.3V)*0.75.
Tramp is 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
device. The risk of latch-up or electrical overstress is small because the only charge
storing in decoupling capacitors is left in the system.

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 Vce and 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.

1. Maximum conditions refer to fast silicon, high temperature and nominal VCC.
2. For 10/100 Mb/s non-stress mode with Intel® AMT, add 12 mW to this number (for example,
using IDE-R functionality).
3. For 10/100 Mb/s stress mode active Intel® AMT, add 120 mW to this number (for example, using
IDE-R functionality).
4. The current use is slightly higher in the device off state than in the no link state. This occurs since
a PHY reset is required in the device off state, which overrides the PHY power down.

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.

Thermal Specifications
The case temperature (TC) is calculated using the equation:
TC = TA + P (⎝JA - ⎝JC)
Junction temperature (TJ) is calculated using the equation:
TJ = TA + P ⎝JA
The power consumption (P) is calculated by using the typical ICC and nominal VCC
where TA represents 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.
