TSW1400 Pattern Generator Operation
5.1
Testing a TSW1400 EVM with a DAC3152 EVM
This section describes the pattern generator operation when testing with a DAC3152 EVM that has a
LVDS input interface.
Power down the TSW1400.
Connect J5 of the DAC3152 to connector J4 of the TSW1400.
Provide +5 VDC to J12 and return to J13 of the DAC3152 EVM.
Provide a 0.5-Vrms, 250-MHz clock to J9 of the DAC3152 EVM.
Power up the TSW1400 EVM
Start up the HSDC Pro GUI as described in the Software Start Up.
A TSW1400 EVM connected to a DAC3152 EVM is shown in Figure 12.
Figure 12. TSW1400 EVM Interfacing to a DAC EVM
NOTE:
The FPGA clocks from DAC EVMs to the TSW1400 EVM have to be LVDS level. Exceeding
LVDS levels may damage the TSW1400 FPGA.
5.2
Loading DAC Firmware
If opening the GUI for the first time, when setting up for pattern generator mode, make sure “DAC” in the
top right side of the GUI is selected. After clicking on “DAC”, the top level GUI shall look as shown in
Figure 13.
