The input to the EVB is an analog audio provided via the RCA input connector J7 or LINE In connector J19 (white). Jumpers J5 and J13 are set to RCA input by default. The user has to change this jumper accordingly if LINE In is being used. Then the analog audio input is routed directly through a switch to the Si47xx Rin/Lin inputs pin 15 and 16 (Audio2). Analog In to Digital In: This configuration provides a way for the user to evaluate the Si47xx digital audio input for FM transmission using an analog audio input. The input to the EVB is an analog audio provided via the RCA input connector J7 or LINE In connector J19 (white). Jumpers J5 and J13 are set to RCA input by default. The user has to change this jumper accordingly if LINE In is being used. Then the analog audio input is converted by CODEC U10 to a serial audio digital data before it is routed to the Si47xx digital audio input DIO and DFS pin 13 and 14 (Audio1). The DCLK input is routed to the GPO3/DCLK pin 17. Make sure that jumper J41 is set to DCLK to ensure proper operation. Digital In to Digital In: This configuration provides a way for the user to evaluate the Si47xx digital audio input for FM transmission using S/PDIF digital audio commonly found in sound cards. The input to the EVB is a digital S/PDIF data provided via the S/PDIF In connector J19 (white). The digital S/PDIF input is converted by S/PDIF Translator U9 to a serial audio digital data before it is routed to the Si47xx digital audio input DIO and DFS pin 13 and 14 (Audio1). The DCLK input is routed to the GPO3/DCLK pin 17. Make sure that jumper J41 is set to DCLK to ensure proper operation. Note: Digital in through J19 will not be supported on new EVBs as of February 14, 2011. The EVB supports three different kinds of configurations for the FM receiver: Analog Out to Analog Out Digital Out to Digital and Analog Out Dual Output (Digital and Analog Out) Analog Out to Analog Out: This configuration provides a way for the user to evaluate the analog audio output for receiver operation. The output of the Si47xx is routed to RCA output connector J6 and Line output connector J30. Digital Out to Digital and Analog Out: This configuration provides a way for the user to evaluate the digital audio output for FM and AM receive using either S/PDIF digital audio or analog audio through the onboard CODEC. The Si47xx digital audio out is routed through the S/PDIF translator µ9 to S/PDIF output connector J30 and routed through the CODEC to RCA output connector J6 and line output connector J30. Note: Digital output through J30 will not be supported on new EVBs as of February 14, 2011. Dual Output (Digital and Analog Out): This configuration provides a way for the user to evaluate the analog audio out and digital audio using S/PDIF digital audio for FM and AM. The analog output of the Si47xx is routed to RCA output connector J6 and line output connector J30 and the digital audio out is routed through the S/PDIF translator to S/PDIF output connector J30. Note: Digital output through J30 will not be supported on new EVBs as of February 14, 2011.

Getting Started 4.1. Software Installation The Si47xx Windows GUI (graphical user interface) software is designed for use with the Si47xx evaluation board (EVB). The GUI software revision number is available under HelpAbout. The GUI software development program uses a host machine USB port to communicate with the Si47xx EVB and is tested for use with Windows XP, Windows 2000, and Windows 7. To install, insert the Skyworks Si47xx CD into the host machine CD drive and launch Windows Explorer. Open the CD to explore the contents in a window like the one shown in Figure 23. Figure 23. Installation and Setup Screen Important: Open and read the Readme.doc file at this point. It may contain information that is not captured here, and which could be very important to the functionality of the EVB or software. Run the Setup.Exe and follow the instructions on the screen. Note: If you get this Error message: "This setup requires the .NET Framework version 4.0," then you should install the .NET Framework that is provided on the CD and re-run the setup. The GUI requires version 4.0; however, multiple versions such as 2.0, 3.0, and 5.0 can be installed simultaneously. After installation is finished, a Skyworks Audio GUI icon will appear on your desktop. Launch the software by clicking this icon on the desktop as shown in Figure 24. Figure 24.

Board Initialization After launching the GUI, you will be shown the initialization window as shown in Figure 25. Note: This window can be accessed at any time by choosing Initialize from the File menu from the main GUI screen. Figure 25. GUI Initialization Screen 4.2.1. Board Selection At the top of the initialization window there is a board selection box, as displayed in Figure 26, that allows the selection of the board that will be controlled by the GUI. This box is populated automatically and will update real time as boards are connected/removed from the PC. If no EVBs are listed in the board selection box, verify that an EVB is connected to the USB port of the PC running the GUI application. After selecting the desired board the GUI will populate the rest of the dialog with options appropriate to the board selected. You will only see modes/options for the type of board that is currently selected. Figure 26.

Board Discovery Bus Mode The initialize process can be configured to use either 2-wire or 3-wire bus mode. This can be configured by selecting File Board Discovery Bus Mode. This feature is useful when using the Skyworks EVB and GUI to control a prototype that is designed to use one bus mode only. 4.2.3. Function Configuration For each mode available on the selected EVB, multiple configuration items (Figure 27) will be present to allow for configuration of the GUI software. It is possible to change these settings to meet testing requirements. The default configuration of the board when you connect it to the computer is acceptable for most users. After initialization, the GUI will save and restore these settings whenever the same type of board is connected. Figure 27. Mode Configuration Items 4.2.3.1. Functions Currently the UI supports four possible functions. These functions are AM Receiver, FM Receiver, WB Receiver, and FM Transmitter. Each function is configured independently from other functions. It is important to configure all functions as desired as it is possible to have FM Receive boot in digital mode while AM Receive boots in analog mode. The currently highlighted function row will be the function that is initialized when the Initialize button is selected. Settings for other functions that are not selected will be saved and used to initialize that function when choosing another function from the UI main window. 4.2.3.2. Boot Mode There are two boot modes possible for each function. It is possible for some boot modes to not be available on some boards. From Device—This option will use the firmware embedded on the device selected. This is the faster of the two options. From File—This option will use the patch functionality of the device to send firmware from a file stored within the UI to the device. If using this option, choose the appropriate firmware in the Firmware column for the function you are configuring. 34 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 0.8 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • October 4, 2021 Si47xx-EVB 4.2.3.3. Default Mode There are two or more default modes possible for each function. Use Last UI State: When selected, the GUI will restore all settings on the device to the previous settings configured in the GUI the last time it was closed. Use Chip Defaults: When selected, the GUI will use the settings that were default in the firmware on the device. Only properties related to the correct setting of RCLK (such as frequency and prescaling) and initial tuning (such as frequency) will be changed. If an error occurs during initialization of a function, choose this setting to default the GUI settings back to the chip defaults. Saved Configuration States: If you have previously saved or imported any configuration states, they will be listed by name. When one of these is selected, the GUI will restore all settings on the device to the previously saved settings. 4.2.3.4. Audio Mode This option allows the user to change between Analog or Digital modes if the board connected supports digital. Sections 2.1.4, 5, 6, and 7 each document the possible settings in more detail depending on what function is being configured. Figure 28 displays the window after the Details button has been pressed which helps with selection of the Audio Mode by displaying a bitmap of the current audio setting in the dialog. Figure 28. Expanded Details Dialog 4.2.3.5. Firmware This selection is only required if "From File" was chosen for the Boot Mode. Use this setting to choose which firmware will be downloaded to the device. If this item turns red then there is no firmware available for the function so "From Device" must be chosen as the Boot Mode.

Bus Mode This setting affects all functions that are configured. It allows the device to be booted either in 2-wire or 3-wire mode. 4.2.3.7. Internal Oscillator When the "Use XOSCEN" is enabled and the board is configured to use the crystal oscillator, the GUI will boot the device using the crystal oscillator. This option is only available on devices that support the crystal oscillator option. 4.2.3.8. Auto Boot when UI Opened and only One Board is Connected When this item is selected, the GUI, when launched, will automatically boot the board if the same board is connected. If more than one board is connected, the GUI will display the initialization dialog to allow selection of the board to initialize. 4.3. Switching Functions After the board has been properly configured for all functions it is possible to switch between functions from the main UI window using the function buttons provided. Only function buttons will appear for the functions supported by the device currently running. Figure 29 highlights the buttons used to switch functions from the main screen. Figure 29.

State Management Once the part has been initialized, a State Management option becomes available in the File Menu. This GUI feature allows the user to save, retrieve, load, and delete the configuration state which contains the property values. 4.4.1. Save Configuration State To save the current configuration state, select FileState ManagementSave Current State. The Select Configuration window shown in Figure 30 will pop up. Enter a name for the configuration state and click OK. The current state that contains the property values is now saved under the given name. If a state already exists with the chosen name, the GUI will give you the option of replacing the original state, entering a different name, or canceling the save. Figure 30. Naming a Configuration State during Save 4.4.2. Retrieve Configuration State Once a configuration state for a part has been saved, it will appear in the Default Mode list in the Initialization window as shown in Figure 31. Select the state you wish to retrieve when initializing the part, and all properties and the tuning frequency of the saved configuration will be restored. Figure 31. Saved Configuration State Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com 37 Rev. 0.8 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • October 4, 2021 Si 47xx- EV B 4.4.3. Load Configuration State When a configuration state for a part has been saved, it will also appear in the Load State list as shown in Figure 32.

Export Saved State In addition to saving, retrieving, and deleting the configuration state, the GUI also gives the end user the ability to export the configuration state to a file. The file can then be imported to installations of the GUI on different machines to allow multiple users to easily implement the same configuration state. To export a saved configuration state to a file, select File State ManagementExport Saved State and the Select Configuration window will pop as shown in Figure 34. Select the configuration state to export and click OK to save the configuration file with a .ini extension. This configuration file can now be exported to different machines. The name of the saved state is retained in the file when exported. Figure 34. Selecting Configuration State to Export 4.4.6. Import Saved State A saved configuration state can be imported from a .ini file exported by another instance of the GUI. To import a saved state, select FileState Management Import State File, then browse for and select the desired file. Once the file has been imported, the saved state will appear in the Default Mode list in the Initialization window. If a state already exists with the same name as the state in the imported file, the GUI will give you the option of replacing the original state, choosing a new name for the imported state, or canceling the import from file. The name appearing in the initialization window will not necessarily be the same as the *.ini file name exported. It will reflect the name of the original state that was exported. 4.5. Disconnecting the EVB The GUI provides three methods for disconnecting the device: Closing the GUI, choosing disconnect from the file menu, or physically disconnecting the device from the PC. When closing the UI or selecting disconnect from the file menu, the GUI will prompt if the device should be powered down or not. This prompt allows for further investigation of the device after the GUI has been disconnected from the EVB. After the board has been disconnected through the File menu, the GUI will save the current state of the device to disk. This state will be used to power up the device in the same state next time the board is connected. The GUI will only save the current state if the board is disconnected through the File menu or the GUI application is closed. If the board is removed from the PC without being disconnected through the File menu and before the GUI is closed, then all state data will be lost.

Configuring the Si47xx as an FM Transmitter Using Digital Audio with Analog Audio Source This mode configures the Si47xx to receive digital audio input at pins 13 and 14 (DIN and DFS), but the user still provides an analog audio source to the EVB. It is useful for a user who wants to test digital input on the Si47xx but does not have a digital audio source. The analog audio source is converted to digital audio through the CODEC, which can be configured to output various digital audio formats. Refer to Figure 41, “CODEC Settings Property Window,” on page 49 to control the CODEC. Configure the desired parameters in the initialization screen and then click Initialize. A new window displaying "Initializing FM Transmitter" will appear. Figure 36.

Program Identification (PI) 2. Program Type (PTY) The GUI makes it easy to send data in three of the following group types: 1. Group Type 0: Program Service (PS) 2. Group Type 2: Radio Text (RT) 3. Group Type 4: Clock Time (CT) It is possible to send data in the other group types, but the user has to manually enter the data in hexadecimal code. Because of the complexity of the RDS/RBDS standard, the explanation of the RDS Transmit Data window is divided into three sections: Basic, Intermediate, and Advanced.

Basic The RDS Transmit Window is divided into three categories: 1. General 2. Program Service 3. Buffers In the basic section, we will cover two out of the three categories: the General and Program Service. In the General category, the user can set the PI and PTY data. In the Program Service, the user can set the PS data (Group Type 0). The following diagram shows a step-by-step explanation: 1 2 3 4 5 Figure 46. Basic RDS Message Illustration 1. First select whether you want to transmit in RDS format (Europe) or RBDS format (US). 2. Type in the Program Identification in this field. Program Identification is a 16-bit code assigned to an individual station. 3. Select the Program Type in the pull down menu here. Some examples include news, information, sports, talk, rock, etc. 4. Enter the Program Service (PS) in the boxes provided. You can enter a maximum of 12 different PS messages, in which each PS message can contain a maximum of 8 characters. a. Repeat Count: Enter how many times you want each PS message to be transmitted before sending the next PS message. b. Message Count: Enter how many of the 12 PS messages that you actually want to transmit. c. Mix: Select 100 percent. 5. Click Send Message button here. Now the RDS will transmit the PS message along with the PI and PTY. You should see these data in your RDS receiver. 56 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 0.8 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • October 4, 2021 Si47xx-EVB 5.10.2. Intermediate In the intermediate section, we will cover the buffers category of sending the RDS data with the device, in particular we will send Group Type 2 (Radio Text) and Group Type 4 (Clock Time). The following diagram shows a step-by-step procedure to send the buffers data in addition to the General and Program Service data covered in the basic section. 1 2 3a 3 5 6 4 Figure 47. Intermediate RDS Message Illustration 1. Select the Mix percentage that you want between transmitting the data in Program Service and the data in the Buffers. A mix percentage of 100% means that you will always transmit the PS message regardless of what is contained in the Buffers, whereas a mix percentage of 0% means that you will always transmit the data in the Buffers regardless of what is contained in the PS. If the buffers are empty, the PS messages will be transmitted all the time regardless of the mix percentage. 2. Enter the Radio Text message that will be transmitted. After entering the RT message, click either the "Add to Circular" button or the "Add to FIFO" button. The RT message will be encoded according to the RDS Group Type 2 rule. a. Clicking "Add to Circular" button means that you add the RT message into the GUI Circular Buffer queue. Note that the message itself has not been uploaded into the Circular Buffer inside the device until the Clear Buff & Send is clicked. b. Clicking "Add to FIFO" means that you upload the RT message into the GUI FIFO Buffer queue. Note that the message itself has not been uploaded into the FIFO Buffer inside the device until the Clear Buff & Send is clicked. 3. Enter the size of the FIFO that you want here. The device buffer has a total of 128 blocks, which is shared by the circular buffer and the FIFO. Therefore, the circular buffer size (shown in 3a) will be the remainder of the 128 blocks minus the FIFO size. 4. Clicking this "Clear Buff & Send" button will upload the message from the GUI Circular Buffer queue into the Circular Buffer inside the device. The Circular Buffer on the part will repeatedly send the message contained in the buffer. Note that the messages in the circular buffer will be transmitted only if the PS Mix value is set to anything other than 100%.

Clicking the "Add Time" button here will add the current time as a RDS Group Type 4 message to the GUI FIFO Buffer queue. 6. Clicking the "Clear Buff & Send" button will upload the message from the FIFO Buffer Indicator Window into the FIFO Buffer inside the device. The FIFO Buffer on the part will only send the messages contained in the buffer once. A good example of using FIFO buffer is when you want to send the time data. Time is something that occurs only once, so it will not be beneficial to upload time to the circular buffer and transmit it continuously. Refer to step 5 for information on sending time data. Note that the messages in the FIFO buffer will be transmitted only if the PS Mix value is set to anything other than 100%. 5.10.3. Advanced In the advanced section, we will cover the remaining RDS topics. 1 2 3 4 5 8 6 7 9 Figure 48. Advanced RDS Sending Illustration 1. Dynamic: This tells whether the PTY code is static or dynamic. 2. Alternate Frequency: This provides the ability to inform the receiver of a single alternate frequency. This field is transmitted along with the Group Type 0 (PS). 3. Miscellaneous bits in Group Type 0 (PS): a. Artificial Head: 0 = Not Artificial Head; 1 = Artificial Head b. Stereo: 0 = Mono; 1 = Stereo c. Audio Compressor: 0 = Not compressed; 1 = Compressed d. Traffic Program (TP): 0 = No TP; 1 = TP e. Traffic Announcement (TA): 0 = No TA; 1 = TA f.

For these messages, the user must encode the messages into hexadecimal code. Circular Buffer Indicator: This displays the message that gets uploaded into the Circular Buffer in hexadecimal code. This can be useful to see how the Group Type 0 (PS), Type 2 (RT), and Type 4 (CT) is encoded into RDS data.

Block Counters Provides the block error rates after tune and after RDS Sync. After Tune Error Rate: After tune (STC interrupt), the ideal number of blocks the FM tuner should have received is calculated. Also, the number of accepted blocks and errors are calculated. Error Rate = number of errors / number of ideal blocks after tune. After Sync Error Rate: After RDS Sync (RDS interrupt), the ideal number of blocks the FM tuner should have received is calculated. Also, the number of accepted blocks and errors are calculated. Error Rate = number of errors / number of ideal blocks after sync Because it usually takes 100~200ms for the FM tuner to synchronize to RDS data (STC interrupt always comes before RDS interrupt), "After Tune Error Rate" will always be greater than "After Sync Error Rate." After a long time, both error rates should consolidate at similar levels. Reset Resets the block counter numbers.

FM Receiver Logging Tools The GUI provides several useful logging tools. In the tools menu, user can choose to log raw RDS data, band scan data, device commands and channel info. Figure 63. Logging Tools 6.10.1. Log Band Scan Selecting ToolsLog Band Scan allows you to specify a filename and begin a scan of the entire band for RDS data, RDS acquisition times, and the contents of each register. The scan feature starts with the first frequency in the band (CHAN = 0) and then seeks to the first station that meets the seek criteria (SEEKTH, SKCNT, SKSNR). When a valid station is found, the software waits at the station for the time specified by ViewSession PreferencesScan Log After Tune Delay (sec) and then checks if RDS is available. If RDS is not available, the software logs the register settings and seeks to the next valid station. If RDS is available, the software waits an additional delay as specified by ViewSession PreferencesScan Log RDS Log Delay (sec). When this delay expires, the software logs the RDS information and register settings and seeks to the next valid station. While scanning, the software displays a green "Scanning" notice below the menu bar. The scan can be aborted by selecting the ToolsLog Band Scan a second time. When the scan completes, the filename given is saved in comma separated format and is available for analysis in a text editor or spreadsheet. 6.10.2. Log Raw RDS Data Selecting ToolsLog Raw RDS Data prompts for a filename in which all RDS data will be logged in comma separated format. The software then logs all raw RDS data that is received, the station it is received on, and the time at which it was received. The logging will continue until ToolsLog Raw RDS Data is selected a second time at which point the file is saved and available for analysis in a text editor or spreadsheet. 6.10.3. Log Channel Info Selecting ToolsLog Channel Info prompts for a filename in which all register values will be logged in comma separated format. The software then logs all register values and the time at which it was received. The logging will continue until ToolsLog Channel Info is selected a second time, at which point the file is saved and available for analysis in a text editor or spreadsheet. 6.10.4. Log Device Commands Selecting ToolsLog Device Commands prompts for a filename in which all software API calls and data with timestamp data will be logged as text. The logging will continue until ToolsLog Device Commands is selected a second time, at which point the file is saved and available for analysis in a text editor. 82 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 0.8 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • October 4, 2021 Si47xx-EVB 6.11.

AM Receiver Logging Tools Info 8.6.1. Log Band Scan Selecting ToolsLog Band Scan allows you to specify a filename and begin a scan of the entire band. The scan feature starts with the first frequency in the band and then seeks to the first station that meets the seek criteria (Seek RSSI Threshold, Seek SNR Threshold). When a valid station is found, the software waits at the station and logs Frequency, AFC, RSSI, SNR, Soft Mute etc settings and then seeks to the next valid station. While scanning, the software displays a green "Scanning" notice below the menu bar. The scan can be aborted by selecting the ToolsLog Band Scan a second time. When the scan completes, the filename given is saved in comma separated format and is available for analysis in a text editor or spreadsheet. 8.6.2. Log Device Commands Selecting ToolsLog Device Commands prompts for a filename in which all software API calls and data with timestamp data will be logged as text. The logging will continue until ToolsLog Device Commands is selected a second time, at which point the file is saved and available for analysis in a text editor. 8.6.3. Log Channel Info Selecting ToolsLog Channel Info prompts for a filename in which all register values will be logged in comma separated format. The software then logs all register values and the time at which it was received. The logging will continue until ToolsLog Channel Info is selected a second time, at which point the file is saved and available for analysis in a text editor or spreadsheet.

Using the EVB with a 9 V Battery The EVB can be used with a 9 V battery that allows the user to disconnect the board from the computer for evaluating the Si47xx. Follow the guidelines listed below to use your EVB with a 9 V battery. 1. Put the switch SW1 in the Ext/Battery position. 2. Connect a 9 V battery to jumper J77. 3. Connect the USB cable. 4. Launch the GUI. 5. Initialize the EVB for AM or FM reception. 6. Once the desired station is tuned and all the settings for the receiver are according to the user's liking, please exit the GUI. 7. When asked whether to leave the device on, please click on yes. 8. Remove the USB cable. 9. The EVB can now be moved around. Note that once the EVB is using its 9 V battery, it is not possible to change the tuned station. Repeat steps 3–9 to tune the EVB to a different station while running on the 9 V battery.

Ensure the EVB is recognized by the PC by right-clicking on My Computer and selecting PropertiesHardwareDevice Manager. Under Human Interface Devices, select each HID-Compliant Device“Details entry and confirm one contains VID_10C4&PID_8244. IF the EVB is not recognized by the GUI, but is recognized by the PC, it is likely that another process has erroneously acquired the handle to the EVB. Two processes known to cause this issue are lxhidsve.exe and EAUSBKBD.exe. Terminate these processes in the Task Manager. If EVB is not recognized by the GUI, uninstall .NET framework 2.0 and reinstall from the installation CD or Microsoft’s website. The GUI requires .NET Framework 2.0; however, multiple versions such as 1.1, 2.0, and 3.0 may be installed simultaneously. The GUI may crash if a previous GUI .ini file was not removed properly. Close the GUI, and delete all .ini files from the GUI directory. Launch the GUI and try again. If the GUI continues to crash, close the GUI, remove the GUI from Control PanelAdd or Remove Programs, and then delete the GUI directory. Launch the GUI and try again.
