    CLIP Signal Name Data Type Control/Indicator Description
    CLK200 — — You must select a 200 MHz clock in the Clock Selections category of the IO Module Properties dialog box for proper CLIP functionality.
    CLK40 — — You must select a 40 MHz clock in the Clock Selections category of the IO Module Properties dialog box for proper CLIP functionality. The User Command and SPI signals should be accessed only in this clock domain.
    Data Clock — — FPGA clock used to sample analog input and output data.
    Data Clock Div 2 — — FPGA clock used to sample analog input and output data. This clock runs at half the rate of Data Clock.
    SPI Idle Boolean Indicator Indicates when the SPI interface to either the clock circuit or ADC is being accessed.

    Use the User Command, User Data 0, and User Data 1 signals to configure your device.

    Refer to the User Command Reference for information about values for this signal.

    User Data 1 U8 Control Specifies configuration for the command in the User Command signal.

    Use the User Command, User Data 0, and User Data 1 signals to configure your device.

    Refer to the User Command Reference for information about values for this signal.

    User Command Status U8 Indicator Indicates whether the previous command completed successfully.
    • 0 = Successful
    • 1 = Command does not exist
    • 2 = Option does not exist
    User Return U16 Indicator Returns data configured by the User Command signal.
    User Error U8 Indicator Indicates that an error occurred and you must reinitialize the device.
    • 0 = No error
    • Nonzero = Error
    AI 0 Data N-1 I16 Indicator Reads analog data from the adapter module.

    Each sample is a left-justified I16 data type.

    AI 0 Data N
    AI 1 Data N-1 I16 Indicator Reads analog data from the adapter module.

    Each sample is a left-justified I16 data type.

    If AI 1 is configured for TIS mode, these signals return time-interleaved samples for AI 1.

    AI 1 Data N
    AO 0 Data N-3 I16 Control Sends analog data to the adapter module.

    Each sample is an I16 data type.

    AO 0 Data N-2
    AO 0 Data N-1
    AO 0 Data N
    AO 1 Data N-3 I16 Control Sends analog data to the adapter module.

    Each sample is an I16 data type.
