RFSA3715
5MHz to 4000MHz, Digital Step Attenuator
Package: QFN, 32-pin,
The RFMD’s RFSA3715 is a 7-bit digital step attenuator
(DSA) that features high linearity over the entire 31.75dB gain
control range with 0.25dB steps. The RFSA3715 features
three modes of control: serial addressable, latched parallel
and direct parallel programming. The RFSA3715 has a low
insertion loss of 1.5dB at 2GHz. Patent pending circuit
architecture providing overshoot-free transient switching
performance. External address pins allow up to eight DSAs to
be controlled on a single bus. The RFSA3715 is available in a
5mm x 5mm QFN package.

Evaluation Board Programming Using USB Interface
Serial Addressable Mode
All programming jumpers on the evaluation board are set to the default values indicated in the table. Refer to the
Control Bit Generator (CBG) Software Reference Manual for detailed instructions on how to setup the software for use.
Apply the supply voltage to P6. Select ‘RFSA3715’ 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. Note that the external address bits must all be set to ‘0’ when using the USB interface as the CGB software
does not have the capability to set the external address in the serial data stream at this time.
Latched Parallel Mode
Evaluation board programming jumper S2 is set to ‘0’. All other programming jumpers are not required and can be set
to any position. Refer to the Control Bit Generator (CBG) Software Reference Manual for detailed instructions on how
to setup the software for use. Apply the supply voltage to P6. Select ‘RFSA3715-P’ 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 Addressable Mode
This configuration allows the user to control the attenuator through the P5 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 P5 connector. Note that the top row of P5 contains the serial bus signals and the bottom row is ground.
Programming jumper S1 is set to ‘0’ and S2 is set to ‘1’. External address jumpers S3 through S5 can be set to any
value desired by the user. Jumper S6 is installed and allows the LE signal to be routed from the P5 connector to the
attenuator. Apply the supply voltage to P6. Send the appropriate signals onto the serial bus lines in accordance with
the Serial Addressable Mode Timing Diagram. The attenuator is set to the desired state and measurements can be
taken.
Latched Parallel Mode
This configuration allows the user to control the attenuator through the P1 connector using an external harness.
Remove the USB interface if it is currently installed on the evaluation board. Connect a user-supplied harness to the
P1 connector. The parallel bus signal names for P1 are indicated on the evaluation board. Programming jumper S2 is
set to ‘0’ to select parallel mode. All other programming jumpers are not required and can be set to any position. Apply
the supply voltage to P6. Send the appropriate signals onto the parallel bus lines in accordance with the Latched
Parallel Mode Timing Diagram. The attenuator is set to the desired state and measurements can be taken.
Direct Parallel Mode
This configuration allows the user to control the attenuator through the P1 connector using an external harness. When
using this mode the LE signal is held at logic high so that the attenuation will change immediately when there is a
change in logic state for any of the parallel bus signals. Remove the USB interface if it is currently installed on the
evaluation board. Connect a user-supplied harness to the P1 connector. The parallel bus signal names for P1 are
indicated on the evaluation board. Programming jumper S2 is set to ‘0’ to select parallel mode. All other programming
jumpers are not required and can be set to any position. Apply the supply voltage to P6. Send the appropriate signals
onto the parallel bus lines. The attenuator is set to the desired state and measurements can be taken.
Default Power-up State
This default attenuation state is maximum (31.75dB) when supply voltage is applied to the attenuator in both serial and
parallel modes. If a different attenuation state is desired during power-up, this can be accomplished by applying signals
according to the Parallel Mode Truth Table. The attenuator will power-up to the state applied to the parallel bus during
turn on. The LE signal must be held to logic ‘0’ during power-up.
