Quick Views of Evaluation Setups for LVDS Interface
The AFE5818 EVM is tested using the TSW1400EVM for LVDS data interface.

Equipment Setup Overview
As shown in
, mating the AFE5818 EVM with a TSW EVM allows for testing using the data
interface.
Figure 3. LVDS Evaluation Setup Overview
TSW Capture Card EVM:
The TSW1400 EVM is required for capturing data from the AFE5818 EVM and
its analysis using the graphical user interface (GUI), called High Speed Data Converter Pro (HSDCPro).
For more information on the TSW1400EVM, see:
Power Supply:
A barrel connector power cable is provided with the EVM and is connected at J1, but
does not support the –5 V needed for the CW mode or Vcntl circuit. This requires an additional cable, not
provided.
This 5-V power supply must be able to source up to 2 A, and –5-V supply must provide up to 1 A. The –5-
V supply is used for the negative supply of amplifiers in the CW output external circuitry and V
cntl
circuit.
The TSW1400 EVM is powered through a power cable similar to
that is provided with its own
EVM kit.
USB Interface to PC:
The USB connections from the AFE5818 EVM and TSW EVM to the PC are used
for communication from the GUIs to the boards. USB 2.0 or 3.0 ports are both acceptable.
