LSF0108 Setup (Out of Box Setup)
Figure 8
shows a typical setup of the LSF-EVM. Note the following connections:
•
VREF_A is connected to J1
•
V_PU is connected to J2
•
A high-speed signal is connected into the SMA Connector on the A side with a 50-
Ω
termination
impedance to reduce line reflections
•
An SMA cable is connected from the B side to a high-impedance oscilloscope input to monitor the
output waveform
•
The yellow cable on the left is connected to A3 on the A side to provide an input signal
•
The yellow cable on the right is connected to B3 on the B side to monitor the output waveform
•
Two red boxes indicate the positions for shunt jumpers placed on J4 which connect pullups for
channels 1 and 3 on the B side for up-translation.
