  • Page 14: Operating Modes

    The following figure has been included to provide the user with a range of frequencies for the possible ADC32RF5xEVM averaging modes. For best performance, at input frequencies less than 800 MHz, it is recommended to use the outer inputs (AIN1 or BIN1) in either of the 1x or 2x averaging modes. At frequencies above 800 MHz, both of the inputs (inner vs outer) yield similar performance.

  • Page 15: Quad Adc Mode

    Operating Modes 5.2 Quad ADC Mode Programming into quad mode enables the functionality of the channel selection menu in the ADC32RF5xEVM GUI. This programming mode must be chosen when the user wants to capture using the inner inputs (INA2, INB2) in 1x or 2x averaging modes.
