TSW1400EVM - ADS4249EVM - DAC5681EVM

Dear Neeraj,

Thank you for your answer,

From your previous answer and Iast answer, I understand that HSDC Pro Software can only talk either DAC or ADC / we can not control ADC and DAC simultaneously from HSDC Pro Software. Because of program limitation, we should use two different computer if we use HSDC Pro Software. I understood this situation in your previous answer and i answer wrote to you to request the alternative solution. Your last answer is also about using HSDC Pro Software. My question is different than what you understand.

I want to control ADC and DAC with program which is written in another language by me. During control, my program will control FPGA(Altera Stratix IV) and it will control ADC and DAC without using the HSDC pro software GUI. My question is at that stage on LVDS interfaces. Is timing process can be done with Altera Stratix IV FPGA while ADC and DAC are connected via LVDS interfaces? Can I control simultaneously them?

During my research, i found a document which is about ‘Interfacing Altera FPGAs to ADS4249 and DAC3482’. I couldn’t find a detailed examination chance yet. By superficial examining this example, i understand that TSW1400EVM can control TI’s high speed ADCs and DACs simultaneously and seamlessly.

Thank you for your answer in advance,

You should be able to capture data and send data at the same time using your own firmware. Both boards are using separate connectors that feed different pins on the FPGA. Are you plan on using internal FPGA memory only? If not, there may be a challenge trying to write and read from the external DDR memory at the same time. Do you need the schematic for this board?

Samet,

I cannot answer this as we have never tried it. I will check with our firmware development team and try to get their opinion on this.

Samet,

Comments from our development team:

Yes, it is feasible. We have also worked on an implementation using TSW1400, where we captured LVDS data from an ADC and transferred it on the DAC port. Here a NI PXI card was replacing the DAC EVM but the application was a simultaneous capture and generation of LVDS data using TSW1400.
