6 Board Setup
6.1 Supply Voltage
The TLV3601 EVM operates using a V
S
(Supply Voltage, or VCC - VEE) from 2.4 V to 5.5 V. Connect VCC
to TP1 and connect VEE to TP2. If using single supply configuration, short both pins of J8 together to connect
GND and VEE. If dual supply configuration is used, leave J8 pins unconnected and make the VCC and VEE
connections previously mentioned, in addition to a GND connection to TP3.

6.2 Inputs
Resistors R1, R2, R3, and R4 are all 0 Ω resistor components. The input terminals (IN+ and IN-) have
corresponding sense lines so that the inputs to the device can be terminated on the lines with 50 Ω to
an oscilloscope. This allows the input signals to be observed with minimal loading and distortion. All input
connections are through SMA connectors. If the input signal to the device does not need to be evaluated on an
oscilloscope, R3 and R4 can be left uninstalled. However, your input signal may need to be terminated if the
oscilloscope's 50 Ω setting is not connected.
The TLV3601EVM has an optional resistor pad on the input (R5) side of the device meant for termination of the
input signal. R5 can be populated with a 100 Ω resistor if applying an unterminated LVDS signal to the board.
