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

DESCRIPTION
P
Efuse Controller Voltage (1.2 V). Must be tied to 1.2 V (DVDD) in the
system application.
LVCMOS 2.5 V
Input
Test Mode Enable Input – Must Be Grounded in the System Application.
Analog Output
SERDES Analog Mux 1 RX – Must be Unconnected/Open in the System
Application
Analog Output
SERDES Analog Mux 0 TX – Must be Unconnected/Open in the System
Application
Resistive
Connection
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 RES1 and GND
Note: These resistors cannot be shared between output pins.
LVCMOS 2.5 V
Input
General Purpose Input – Must be Grounded in the System Application.
General Purpose Outputs – Must be Unconnected/Open in the System
Application.
LVCMOS 2.5 V
Output
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.
