AFE7951: ADC Output / DAC Input Sign Format

Part Number: AFE7951

Tool/software:

1. Is the ADC output of the AFE7951 represented as unsigned or signed integers?

2. Is the DAC input of the AFE7951 represented as unsigned or signed integers?

3. When RF signals are applied to the four ADCs of the AFE7951, how is the ADC output structured?

  • Are the ADCs outputting sequentially, 8 bits each?
    (e.g., 8-bit output from ADC_1 → ADC_2 → ADC_3 → ADC_4)

  • Or do all 4 ADCs output data simultaneously in serial format?
    If it is serial, how are the 8 output ports connected?

4. How is input data applied to the four DACs of the AFE7951?

  • Do we need to input 8 bits sequentially to each DAC?
    (e.g., 8-bit input to DAC_1 → DAC_2 → DAC_3 → DAC_4)

  • Or should all 4 DACs receive input simultaneously in serial format?
    If so, to which input ports should the serial data be connected?

  • Hi,

     

    Thank you for choosing TI High Speed Converter products. I am sorry to inform that our applications team for high speed data converters does not have the bandwidth available to support University inquiries at this time. If resource bandwidth becomes available, we will follow up with this question.
