AFE7444: "DAC Jesd configuration"

Part Number: AFE7444
Other Parts Discussed in Thread: AFE7686,

I want to use DAC Jesd mode (L_M_F_S_HD 1TX = 22210x24 HBW).

The datasheet says that the mode (22210x24 HBW ) is available, but "Register Programming for JESD and Interpolation Mode" doesn't have a value for that item.

According to the "register set Manual", the following calculation was applied, but a Jesd configuration error occurred.







This value is the value that worked normally in the previous AFE7686.

I hope for your help in this regard.

thank you

  • Hi Jong-min,

    I believe that the mode you are requesting is similar to Mode 6 mentioned in the datasheet. Once you load Mode 6 using the AFE7444 GUI you should be able to see how the registers are configured for your mode of interest.
