  • DAC38J82: lane errors not same

    TI Thinks Resolved
    Part Number: DAC38J82 Hello, I have got the register from 0x64 to 0x6C. Below is the value. Reg 0x64 = 0x0001 Reg 0x65 = 0x0001 Reg 0x66 = 0x0001 Reg 0x67 = 0x0001 Reg 0x68 = 0x7709 Reg 0x69 = 0x0001 Reg 0x6A = 0x0001 Reg 0x6B = 0xBD07…

  • DAC38J82: reference design about TI_204c_IP

    Part Number: DAC38J82 Hello, I am reading the reference design(zc706_8b10b) about TI_204c_IP. I have a question about sysref. In TI_204c_IP_ref.sv, I see the Sysref signals tied to '0', like below. So why do like this in reference design? …

  • DAC38J82: DAC38J82 output issue in complex input

    Part Number: DAC38J82 Hello All, I'm working with DAC38J82 in a customised hardware. I'm having an issue in getting the DAC output. Here is my configuration. DAC input clock is 2457.6MHz. DAC PLL is not used. No SYSREF input. I'm trying to use the…

  • DAC38J82: The internal PLL is not working properly

    TI Thinks Resolved
    Part Number: DAC38J82 Hi team, The DAC works without the internal phase-locked loop. The sample clock cannot be generated using the internal PLL, read config108 0x0003. Input clock is 250M and it's required to generate 1GHz sampling clock. The following…
