Apply the supply voltage to P3. Select QPC6614 from the RFMD Parts List of the CBG user interface. Set the attenuation value using the CBG user interface. The attenuator is set to the desired state and measurements can be taken. Evaluation Board Programming Using External Bus Serial Mode This configuration allows the user to control the attenuator through the P1 connector using an external harness. Remove the USB interface board if it is currently installed on the evaluation board. Connect a user-supplied harness to the P1 connector. Note the top row of the P1 contains the serial bus signals and the bottom row is ground. Apply the supply voltage to P3. Send the appropriate signals onto the serial bus lines in accordance with the Serial Mode Timing Diagram. The attenuator is set to the desired state and measurements can be taken. Default Power-up State The attenuation state set during power-up can be controlled using the PUP2 pin. To power-up in the maximum attenuation state, apply a logic low to PUP2 pin prior to applying supply voltage VDD. To power-up in the minimum attenuation state apply a logic high to the PUP2 pin prior to applying supply voltage VDD.
