Signal Description
Digital Power Supply - Core.
+2.5 V supply for core digital circuits.
Digital Power Supply - I/O Ring.
+2.5/3.3 V supply for digital I/O circuits. The digital
input circuits running off of this rail, having a TTL-level
threshold and over-voltage protection, may be
interfaced with 3.3/5.0 V, when the IO supply is 3.3 V,
and 2.5/3.3/5.0 V when 2.5 V.
Digital Power Supply - PECL Signal Detect Inputs.
+2.5/3.3 V supply for PECL Signal Detect input
circuits. If Fiber Mode is not used (that is, G_FX/TP_L
is pulled Low), the VCCPECL pins may be tied to
GNDPECL to save power.
Analog Power Supply - Receive.
+2.5 V supply for all analog receive circuits.
Signal Description
Port 5 LED Drivers 1-3.
These pins drive LED indicators for Port 5. Each LED
can display one of several available status conditions
as selected by the LED Configuration Register (refer
to
Hex 14), on page 204
Port 6 LED Drivers 1-3.
These pins drive LED indicators for Port 6. Each LED
can display one of several available status conditions
as selected by the LED Configuration Register (refer
to
Hex 14), on page 204
Port 7 LED Drivers 1-3.
These pins drive LED indicators for Port 7. Each LED
can display one of several available status conditions
as selected by the LED Configuration Register (refer
to
Hex 14), on page 204
