  • DAC5681(z) SYNC input: functional conflict when combining SYNC and TX_ENABLE function in one pin?

    Resolved
    Other Parts Discussed in Thread: DAC5681 Hello, The DAC5681(z) datasheet describes the "SYNC" input as being dual-use: it must be '1' to enable DAC output. A zero on that input is stored in the internal FIFO along with the data and the DAC output…

  • External DCLKP/N for DAC5681

    Resolved
    Other Parts Discussed in Thread: DAC5681EVM , DAC5681 Hi All, As I look more closely to the board, I notice that R122 and R123 are not loaded, so this clock does not go to DCLKP/N (pin 25,26). It has CLOCK = (DACCLOCK)/2. My question is : where does it…

  • RE: DAC5681Z: IF System

    Resolved
    The DAC5681 is real interface only. The diagram referenced above represents the I/Q in the FPGA or ASIC that will complete the DUC operation before sending the data to the DAC. --RJH

  • RE: Current steering DAC evaluation board

    Shantanu, I think you best bet would be to use the DAC5681 device. The DAC5681EVM does not have an FMC connector, but TI sells a HSMC-to-FMC adapter that would allow the DAC board to be used with a FMC connector. Before purchasing these though, I would…
