DESCRIPTION
AVDD
Transmit Differential Pairs, XAUI Lane, High speed serial outputs. The
CML Output data rate of these signals is from 600 Mbps minimum to 3.75 Gbps
maximum.
AVDD
CML Input
Receive Differential Pairs, XAUI Lane, High speed serial inputs with
on-chip 100 ohm differential termination. Each input pair is terminated
differentially across an on chip 100 ohm resistor. The data rate of
these signals is from 600 Mbps minimum to 3.75 Gbps maximum.

DESCRIPTION
Efuse Controller Voltage (1.2 V). Must be tied to 1.2 V (DVDD) in the
system application.
Test Mode Enable Input – Must Be Grounded in the System
Application.
SERDES Analog Mux 1 RX – Must be Unconnected/Open in the
System Application
SERDES Analog Mux 0 TX – Must be Unconnected/Open in the
System Application
HSTL Impedance Control Resistors – 0.5% Tolerance Resistor
required of the following values:
150 Ohms between RES4 and GND
150 Ohms between RES3 and GND
50 Ohms between RES2 and GND
50 Ohms between RES1 and GND
Note: These resistors cannot be shared between output pins.
General Purpose Input – Must be Grounded in the System
Application.
General Purpose Outputs – Must be Unconnected/Open in the
System Application.
It is recommended that these output ports go to headers or
non-populated resistor pads to facilitate probing of internal device
functions/settings during the initial system bring up process.
Also, to monitor PRBS testing real time, these outputs must be
available for probing on the application board.
