    Hi Gang,

    Programmming of input format and output format are covered in section 4 and 5 of the LMH1982 datasheet. Also refer to Table 1.

    You can also download the Eval software GUI which shows register programming for different input and output formats.

    Hi Alan,

    I understand from the data sheet that there is a suggested sequence that the registers should be programmed.

    Is there a way of showing the sequence and register values that are generated when using the LMH1982 Application v2.0 program without using the USB interface, as I do not have an evaluation board.

    This sequence information would make it far easier to program the LMH1982 using the I2C interface of the microcontroller.

    regards

    John
