DAC34H84EVM: TSW1400 DAC34H84

Part Number: DAC34H84EVM
Other Parts Discussed in Thread: DAC34H84, AFE5809, DAC3484

After reading dozens of disparate (and desperate) requests for support on the TSW1400/DAC34H84 board combination I am still unable to get even the most rudimentary output from the DAC34H84 board. Since I intend to use the DACs at low frequencies I have installed pin compatible low frequency Mini-Circuits transformers on all channels.

I'm assuming the use of the internal clock (DAC JP5 pins 2-3 - any other changes to jumpers required?) to perhaps generate a 1Mhz DAC output square, sine, ramp ... wave output - anything to get a basic output to confirm the board set is working (just in case it matters I have AFE5809 EVM attached to the TSW1400 which IS working fine).

Can you provide me with a step by step example (perhaps with associated files) to make a very rudimentary confirmation that the board set is working (even just one channel)?

It seems unclear where some of the DAC34H84 config file examples reside (as opposed to DAC3484 examples). 

I'm never quite sure when the DAC3484 is referenced what pertains and what does NOT pertain to the DAC34H84.

As far as the explanation of the DAC3484/DAC34H84 GUI it seems I am unable to find a complete reference that explains the various settings in a single document.

  • Hi Dean,

    Following section 3.4 and 3.4 of the user's guide as the basis of the step by step guide.

    you will need to load the following file from the directory:

    C:\Program Files (x86)\Texas Instruments\DAC348x\EVM Configuration File Released

    Everything you need to know about the major differences of the EVMs are explained in the user's guide. Besides the speed and channel count difference, the EVM clocking set up are explained in the following

    If there are other specific problem, please let us know
