Si47xx-EVB 2. Description Si47xx EVB consists of a baseboard, a daughtercard with the Si47xx part pre-mounted, and, if applicable, an antenna card. The baseboard is common and shared among all Si47xx EVBs. The following sections refer to both the images in the figures and the silkscreen on the Si47xx EVB. Please refer to both when using this guide.

Page 10 Si47xx-EVB The Si47xx EVB can be powered using one of the following power supply options: 1. USB power supply via J79 2. External dc (Ext DC) power supply via power jack J78 or battery via J77 3. Three separate power supplies (Vdd, Vio, Vmcu) via terminal block J76 The EVB has three supply rails: Vdd, Vio, and Vmcu.
Page 11 Figure 5. MCU Block Diagram The Si47xx EVB uses a Silicon Laboratories' C8051F342 microcontroller to control the Si47xx and to provide USB connectivity from the host PC (via connector J79). The LED D1 illuminates to confirm that power is being properly supplied to the C8051F342 and firmware has loaded.

Reference Clock Block Diagram The Si47xx accepts a 32.768 kHz reference clock at the RCLK pin. On the EVB, this clock is provided by a precision crystal oscillator.
Page 13 Si47xx-EVB The EVB supports three different kinds of configurations for the FM transmitter:  Analog In to Analog In  Analog In to Digital In  Digital In to Digital In Analog In to Analog In: This configuration provides a way for the user to evaluate the analog audio input for FM transmission.
Page 14 Si47xx-EVB IMPORTANT: Jumper Settings Because of the many possibilities available to configure the EVB, ensure that these four jumpers are set accordingly: 1. J41: GPO3/DCLK setting 2. J44: TX/RX setting for Audio1 I/O (automatically set by the GUI for baseboard 1.3 and later) 3.

Windows XP, Windows 2000, and Windows 7. To install, insert the Silicon Laboratories 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.
Page 33: Board Initialization
Si47xx-EVB 4.2. 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.
Page 34 Si47xx-EVB 4.2.2. 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 Silabs EVB and GUI to control a prototype that is designed to use one bus mode only.
Page 35 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.
Page 36: Switching Functions
Si47xx-EVB 4.2.3.6. 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.
Page 37: State Management
Si47xx-EVB 4.4. 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.
Page 38 Si47xx-EVB 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. Select the state you wish to load, and all properties and the tuning frequency of the saved configuration will be restored without doing initialization to the chip.
Page 39: Disconnecting The Evb
Si47xx-EVB 4.4.5. 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.

Si47xx-EVB 5.10. FM Transmitter Radio Data Service (RDS) The RDS/RBDS feature is available with the Si4711/13/21. This user guide assumes that the user is already familiar with the RDS/RBDS standard. If necessary, the user may refer to the following documents to become familiar with the RDS/RBDS standard.

Page 55 Si47xx-EVB There are 16 different group types in the RDS/RBDS standard, and for every group the following information is always transmitted: 1. Program Identification (PI) 2. Program Type (PTY) The GUI makes it easy to send data in three of the following group types: 1.
Page 56 Si47xx-EVB 5.10.1. 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.
Page 57 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.
Page 58 Si47xx-EVB value is set to anything other than 100%. 5. 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.
Page 59 Si47xx-EVB uploaded means that the RT is uploaded with the flag set. Un-checking this box when an RT is uploaded means that the flag is not set. This flag tells the receiver that when the flag toggles from set to reset or vice versa, the receiver will clear the display before showing the next RT.

Page 83: Fm Receiver Configuration Helper
Si47xx-EVB 6.11. FM Receiver Configuration Helper The configuration helper is a useful tool for configuring the thresholds related to RSSI based Blend, SNR based Blend, Multipath based blend, SNR based hi-cut, Multipath based hi-cut, and Soft Mute. Figure 64. FM Configuration Helper Figure 65.
Page 84 Si47xx-EVB Table 21. Configuration Helper Window Descriptions Item Description Select Parameter Selects between Hi-cut Multipath (Si4706/4x only), Hi-cut SNR(Si4706/ 4x only), SoftMute, Stereo blend Multipath (Si4706/4x only), Stereo Blend RSSI and Stereo Blend SNR (Si4706/4x only). Hi-cut/ Blend/Soft Mute Graph The plot displays the device threshold and rate settings, current signal conditions, and the calculated audio conditioning.
Page 85 Si47xx-EVB Figure 66. FM Configuration Helper Window (SNR Based Hi-cut) In the example shown in Figure 66, the current level marker shows that hi-cut filter is set at 6 kHz. This is determined by both SNR and multipath conditions. Current SNR is 5 dB. Hi-cut SNR Low Threshold is set at 15 dB and hi-cut minimum frequency is set at 6 kHz.
Page 86 Si47xx-EVB Figure 67. FM Configuration Helper Window (Softmute) In the example shown in Figure 67, the current level marker shows that Soft Mute level is 0 dB. SNR threshold is programmed as 4 dB and max attenuation is 16 dB. Since the SNR reported by the part is 5 dB, which is above the threshold, the softmute level is 0 dB.
Page 87 Si47xx-EVB Figure 68. FM Configuration Helper Window (SNR Based Blend) In the example shown in Figure 68, the Current Level marker shows that Stereo % is 56%. SNR threshold is programmed as 14 dB (and below) for full mono and 30 dB (and above) for full stereo. Since the SNR reported by the part is in between the thresholds, the stereo level is 56%.
Page 88 Si47xx-EVB Figure 69. FM Configuration Helper Window (RSSI Based Blend) In the example shown in Figure 69, the Current Level marker shows that Stereo % is 56%. RSSI threshold is programmed as 30 dBµV (and below) for full mono and 49 dBµV (and above) for full stereo. RSSI reported by the part is in between the thresholds however the final blend percentage is determined by SNR and the stereo level is 56%.
Page 89 Si47xx-EVB In the example shown in Figure 70, the Current Level marker shows that Stereo % is 50%. Multipath threshold is programmed as: 60% (and above) for full mono and 20% (and below) for full stereo. Multipath reported by the part is 11% which would put the part in full stereo.
