  • DAC38J84: Is SYNCb used?

    Resolved
    Part Number: DAC38J84 Tool/software: In the DAC38J84 specification, it is mentioned that only JESD204B subclass 1 is supported. Since the SYNCb signal is exclusively used by subclass 2, does this mean that this signal and all related configurations are…

  • DAC38J84: DAC register is all 0 when software reset

    TI Thinks Resolved
    Part Number: DAC38J84 Tool/software: Hi team, This is FAE Jayden, My customer got a question about DAC38J84. When my customer frequently performs software reset operations (not power-off reset) on the whole platform, initialization fails and the DAC register…

  • DAC38J84: IBIS-AMI Rx Mask

    Part Number: DAC38J84 Tool/software: Hi! We are currently evaluating the SerDes link performance of an FPGA to the DAC38J84 in ADS simulation. We are utilizing the IBIS-AMI kit associated with the DAC38J84. We were expecting a mask to be associated with…

  • RE: DAC38J84: can the Fullscale current be adjusted to less than 10mA through the Coarse dac register?

    Rannie, We cannot ensure the accuracy (DNL/INL) and the linearity (IMD3/5) beyond the specifications.

  • DAC38J84: QMC configuration for qmc-phaseab

    TI Thinks Resolved
    Part Number: DAC38J84 Tool/software: Hi team, My customer is using DAC38J84 QMC function. They configure the register like below. When set the config16(qmc_phaseab) to 0x7ff or 0x800, the QMC don't work, and the IQ waveform is abnormal. Could you…

  • DAC38J84: IBIS Model Termination Included?

    Part Number: DAC38J84 Tool/software: Hi all, I am investigating the DAC38J84, and I noticed that the S4P files associated with the part seem to have the termination resistors embedded inside the part. However, the IBIS model has an external termination…

  • RE: DAC38J84: Can 1 or 2 lanes be used without interpolation?

    Resolved
    Greg, That makes sense. Appreciate the insight. I'll feed this back to systems so in the future we can try to support these types of modes. Matt

  • DAC38J84: temp sensor

    TI Thinks Resolved
    Part Number: DAC38J84 Hi, I am using DAC38J84 component in my design. I have checked two different cards with a thermal camera and compared the case temp. to the internal temp. sensor. The case temperature of the DAC was the same (in both cards) but there…

  • LMK04828: Increasing the output clock speed for DAC38J84

    Part Number: LMK04828 Hello, I am currently working with the LMK in conjunction with the FMC144 card from Abaco. While the DACs theoretically can reach up to 2.5 GHz, they are currently stuck at their default frequency of 368.64 MHz. I'm utilizing a C…

  • DAC38J84: FIFO empty alarm in all lines.

    Part Number: DAC38J84 Hi all, I am trying to configure the DAC38J84 in a custom board. I have the DAC PLL locked and the PLL serdes locked but I am getting the FIFO empty error no matter what I try. This is my configuration of the JESD IP core: To sum…
