Apply the supply voltage to P3. Select RFSA3413 from the Qorvo Parts List of the CBG user interface. Set the attenuation value using the CBG Graphic User Interface (GUI). The attenuator is set to the desired state and measurements can be taken. RFSA3413 Programming by Using Its Parallel Bus 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 usersupplied harness to the P1 connector. The parallel bus signal names for P1 are indicated on the evaluation board. Cross reference for device pin names to P1 connector signals is as follows: C1 = D2, C2 = D3, C4 = D4, C8 = D5. Apply the supply voltage to P3. Send the appropriate signals onto the parallel bus lines in accordance with the Parallel Interface Attenuation Truth Table. The attenuator is set to the desired state and measurements can be taken. Power-up State The default state is minimum attenuation (0dB) when supply voltage is applied to the attenuator. If a different attenuation state is desired during power up, this can be accomplished by applying signals according to the Parallel Interface Attenuation Truth Table. The attenuator will power up to the state applied to the parallel bus during turn on.
