Signal Description
_
Digital Power Supply - Core. +2.5V supply for core digital circuits.
Digital Power Supply - I/O Ring. +2.5/3.3V supply for digital I/O
circuits. The digital input circuits running off this rail, having a TTL-
_
level threshold and over-voltage protection, may be interfaced with
3.3/5.0V when the I/O supply is 3.3V, and 2.5/3.3/5.0V when the I/O
supply is 2.5V.
Digital Power Supply - PECL Signal Detect Inputs. +2.5/3.3V
_
supply for PECL Signal Detect input circuits. If Fiber Mode is not
used, tie these pins to GNDPECL to save power.
Analog Power Supply - Receive. +2.5V supply for all analog
_
receive circuits.
Analog Power Supply - Transmit. +2.5V supply for all analog
_
transmit circuits.
Digital Ground. Ground return for core digital supplies (VCCD). All
_
ground pins can be tied together using a single ground plane.
Digital GND - I/O Ring. Ground return for digital I/O circuits
_
(VCCIO).
Digital GND - PECL Signal Detect Inputs. Ground return for
_
PECL Signal Detect input circuits.
Analog Ground - Receive. Ground return for receive analog
_
supply. All ground pins can be tied together using a single ground
plane.
Analog Ground - Transmit. Ground return for transmit analog
_
supply. All ground pins can be tied together using a single ground
plane.
Substrate Ground. Ground for chip substrate. All ground pins can
_
be tied together using a single ground plane.

Signal Description
Port 0 LED Drivers 1-3. These pins drive LED indicators for Port
OD, TS,
0. Each LED can display one of several available status conditions
SL, IP
as selected by the LED Configuration Register.
Port 1 LED Drivers 1-3. These pins drive LED indicators for Port
OD, TS,
1. Each LED can display one of several available status conditions
SL, IP
as selected by the LED Configuration Register.
I
Auto Negotiation Enable. When this pin is High, auto-negotiation
is enabled on the relevant port.
