Signal Description
Analog Power Supply - Receive.
+2.5 V supply for all analog receive circuits.
Analog Power Supply - Transmit.
+2.5 V 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.
