e1 This device is lead-free. That is, lead has not been intentionally added, but lead may still exist
eas an impurity at <1000 ppm. The Material Declaration Data Sheet, which includes lead
himpurity levels and the concentration of other Restriction on Hazardous Substances (RoHS)-
banned materials, is available at:

SIn addition, this device has been tested and conforms to the same parametric specifications as
taprevious versions of the device.
For more information regarding lead-free products from Intel Corporation, contact your Intel
aField Sales representative.
.DAdditional Features
■ The 82562G PLC supports drop-in replacement with the 82562ET. If it is not used as a drop-
in replacement, strapping options enable new operating modes:
w—LED support for three logic configurations.
— LAN disable function using one pin.
w—Increased transmit strength.
m■ The receive BER performance increases the margin for cable length.
w o■ Return Loss performance is improved.

Networking Silicon — 82562G
Introduction
This document is applicable to the Intel® 82562G 10/100 Mbps Platform LAN Connect device, a
member of the 82562G Fast Ethernet device family.
Overview
The Intel® 82562G 10/100 Mbps Platform LAN Connect is a highly-integrated device designed for
10 or 100 Mbps Ethernet systems. It is based on the IEEE 10BASE-T and 100BASE-TX standards.
The IEEE 802.3u standard for 100BASE-TX defines networking over two pairs of Category 5
unshielded twisted pair cable or Type 1 shielded twisted pair cable.
The 82562G complies with the IEEE 802.3u Auto-Negotiation standard and the IEEE 802.3x Full
Duplex Flow Control standard. The 82562G also includes a PHY interface compliant to the current
platform LAN connect interface.

3.0 Performance Enhancements
3.1 New Usage Modes: 1, 2, 3, and 4
82562G supports several new features that offer design flexibility and reduced BOM cost
compared to the 82562ET PLC device. To implement these new features, a board design must
include the proper pull-up and/or pull-down strapping resistor options. Refer to the 82562GT/
82562GZ/82562GX/82562G LAN on Motherboard Design Guide for more information. Table 3
lists the four new modes.
Table 3. Usage Modes 1, 2, 3, and 4
Mode
Benefit
Mode 0: 82562ET compatible.
Mode 1: LED configuration B and single-
pin LAN disable.
No BOM changes necessary for equivalent performance to
82562ET.
Usability and reduced BOM cost.
Mode 2: Same as mode 1, except LED
configuration C.
Mode 3: LED configuration B, Single Pin
LAN Disable, and enhanced Tx modea
Mode 4: Same as mode 3, except LED
configuration C.
See table note a.
Usability and reduced BOM cost.
Usability, reduced BOM cost, and stronger Tx drive strength.
Refer to Section 3.1.2.
Usability, reduced BOM cost, and stronger Tx drive strength.
Refer to Section 3.1.2.
a. Only use this mode if advised to do so by an Intel representative to compensate for board design issues affecting IEEE
compliance.
3.1.1
Pin Usage for Modes 1, 2, 3, and 4
To use modes 1, 2, 3, or 4, the following pins need to be reviewed (refer to Table 1):
• ISOL_TCK
• ISOL_TI
• ISOL_EX
• TESTEN
• ADV10/LAN_DISABLE# and supporting circuits
• ACTLED#, SPDLED#, and LILED# and supporting circuits
