Using TSW1400EVM Eval board to test custom ASIC

Hello,

I am involved in a project requiring me to design and test DACs. We are in process of getting the chip fabricated sometime soon. Now I need to test the DAC with LVDS input from any evaluation board. I am thinking of using TI TSW1400EVM Eval board to test but the web page says that it is compatible with ADCs and DACs listed under the related devices section. That section lists only ADCs and DACs from TI. Can I use this eval board to test my ASIC as well?

Please advise. Thank you.

Regards,

Nikhil

    Nikhil,

    If your ASIC has the same interface as the TI DAC's and ADC's that are listed under the device section I see no problem with this. When you start the TSW1400 GUI, you will need to select a device from the drop down menu to load the firmware into the onboard FPGA. If your ASIC does not support one of these interfaces, you will have to generate your own interface and load the custom firmware using the the "Instrument Option" tab and select "Download Firmware". This option allows the user to load the onboard FPGA with their own firmware. This file must be in .rbf format though.

    Hi Jim,

    We are designing custom high speed DAC ASIC. The input uses LVDS standard. The ASIC has the LVDS pads followed by the receiver which provides input to 8 bit DAC. I am not sure what you mean by interface. Is it the LVDS that you are talking about? If it is some other interface can you please elaborate.

    Thanks.
