5.8. Configuring Tuner Properties
As described in the Programming Guide, various tuner aspects are configured through either a command/response
or get/set property API interface. The GUI contains a window to help manage properties under Window
Properties as shown in Figure 25. “Properties Window”.
Figure 25. Properties Window
Properties are grouped by category. Properties specific to the Si477x device are prefixed with either FM or AM. FM
RDS Settings, FM UI Settings, and AM UI Settings are categories that are used to control UI behavior but do not
modify the property settings on the Si477x device. To see all properties associated with the Si477x device, choose
FM: All or AM: All: All, depending on what mode the device is powered up into.
Most properties included in the API are also included in the properties window. Clicking on a particular property
opens a brief description of the property and its arguments. Refer to the Programming Guide for detailed
information on the properties and values.
Property addresses and values can be displayed or hidden using the Display/Hide Details button. When displayed,
all of the current properties can be viewed or exported to a file (using the Export Properties button) and the last
property changed is displayed. By clicking the Export Properties button shown in Figure 25, the properties can be
exported to a .csv file.

5.9. Register Read/Write
The software's graphical user interface and property windows provide an easy, intuitive method of configuring the
device. In development, however, it is often useful to have low-level bytewise read/write interface to the tuner. The
GUI provides this interface under Window Register Map.
Figure 26. “Register Map Window” shows an example read/write operation. The FM_RSQ_STATUS request is sent
with an ARGument of 0x00. The reply returned in the RESPonse fields.
Refer to the Programming Guide for detailed information on the register definitions and their arguments and
responses.

5.10. Other Useful Tools
5.10.1. RSSI/SNR Graphing Utility
The Graphing utility Window RSSI/SNR Graph provides a scan of user selectable metrics versus frequency.
Graphing options include RSSI, SNR, Low Adjacent Channel Strength (LASSI), and High Adjacent Channel
Strength (HASSI). These metrics can be individually selected for display. A line or bar graph style can be chosen
and markers indicating valid stations and their frequencies can be displayed. Once the preferred graphing and
displays have been selected, click the “Draw” button.
Figure 27 shows an example scan in the FM band. Stations above the red line meet the RSSI threshold for valid
stations. The SNR page shows a complementary scan of SNR values across the band as well as the SNR
threshold for valid stations.
Figure 27. RSSI/SNR Graphing Utility
Rev. 0.3
23
Si477x-EVB
5.10.2. Blend/Hicut/Soft Mute Configuration Helper
The mitigation engines such as FM stereo/mono blend, hi-cut, hi-blend, and soft mute have configurable low- and
high-end thresholds. These thresholds may be configured numerically through the Properties page or graphically
through the Configuration Helper.
Figure 28 shows an example of the Configuration Helper set to display FM stereo/mono blend based on RSSI. This
example also provides the ability to set the Fast and Slow metrics on the same screen. If a configuration setting
does not have Fast and Slow metrics available, only one graph and column of configurable values will appear. On
both graphs the green line depicts the blend (in percent stereo). The green point shows the current operating point
of the receiver (30 dBuV RSSI which results in 18% stereo given the property settings). The cyan line reflects the
actual reported stereo value (14%) from the Si477x device which is mitigated by all the metrics (RSSI/Multipath/
USN) in this example. Since the cyan line is tracking the green point or RSSI mitigated blend, the device is limiting
stereo based on RSSI in this example.
When selecting a mitigation control item, the description text is updated automatically. The name of the property
being changed is displayed in bold. The property can then be found in the property window by finding the property
with the same name being displayed in the configuration helper.
Changes made to this page are applied to the tuner immediately, making it a useful tool in real-time configuration of
the mitigation engines.

6.2. Daughtercard
Each evaluation kit will be provided with an Si477x daughtercard.
Each daughtercard contains the minimal application circuit, including the following:
Si477x
Tuner IC
RF Input circuitry
Crystal
EEPROM for serial number, calibration constants, and crystal information
Each daughtercard features a number of test points with direct access to the tuner signal pins. These signals may
be disconnected from the baseboard connector by removing either a 0 jumper or by removing a solder dot on a
printed chevron pattern. Small vias allow for connection via wire-wrap wire.
The reference frequency is generated by the on-chip crystal oscillator by default. If desired, the reference clock
may be sourced by the baseboard oscillator or an external generator by removing the crystal and inserting a 0.1uF
capacitor to bridge the connection.
Refer to "7. Hardware Schematics and PCB Layout" on page 32 for daughtercard schematics and PCB layouts.
6.3. Baseboard
The Quark baseboard contains all support circuitry, including the following:
Power
supplies: all four Si477x supplies derived from USB 5 V or wall pack 9 V supplies
USB HID-based communications interface via C8051F340 microcontroller
Test points for all tuner interface I/O lines
Direct and buffered L/R/MPX analog outputs
6.3.1. Power Supplies
On-board LDOs generate VA, VD, VIO1, and VIO2 supplies for the tuner. Three of these, VD, VIO1, and VIO2, are
adjustable via trimpot. Level translation to other blocks, such as the microcontroller, is via discrete translators.
Switch SW1 selects the LDO configuration as sourced from the 9 V coaxial connector or the USB 5 V supply from
the PC. When in the USB position, the 5 V analog supply to the tuner is derived directly from the PC USB supply.
Notes:
The
USB power supply option is provided for convenience but may result in decreased RF performance
due to PC power supply noise and lack of regulation between PC and the tuner's analog power supply.
Regulation inaccuracy and cable loss may result in a VA supply voltage below specification.
Ensure any wall power supply has a maximum output voltage of less than 11 V. Higher voltages will
engage a clamping diode and may damage the LDOs.
Jumpers, shown highlighted in Figure 32. “Power Supply Jumpers”, select each tuner supply's source as either the
on-board LDO (shown) or external (via J1/J2).
Tuner supply currents may be measured by opening jumpers J9-J12 and inserting an ammeter in positions JP8JP11.

6.3.2. Microcontroller/USB Interface
Communication to the tuner and configuration is through firmware on a Silicon Laboratories C8051F340 USB
microcontroller. This device translates USB commands via HID interface to I2C control words to the tuner.
PB1 resets the microcontroller.
LED's D3–D6 are driven by the microcontroller. The green LED D4 lights when the microcontroller has booted.
The USB connection may be disconnected once the tuner is configured. Tuner settings will persist until reset or the
power is removed.

6.3.3. Headphone Amplifier/Buffer
Left and Right audio outputs are buffered and lowpass filtered by on-board amplifiers in Figure 33. “Audio Output”.
The software automatically selects the L/R audio-band output when AM or FM modes are selected. The left
channel/MPX output is selected in MPX mode only.
Unbuffered L/R outputs are available at the debug header J48.
Note: Use L/R outputs directly from tuner for THD, SINAD, and stereo imbalance measurements. The headphone amplifier
may degrade performance.
The analog L/R and MPX outputs are available at two 3.5 mm jacks. The function of each jack varies by baseboard
revision.
The left jack is a direct, dc-coupled L/R/MPX output from the tuner. This output should be used for all low-distortion
laboratory measurements. The right jack is an ac-coupled, unity-gain-buffered L/R output for listening through
headphones or powered speakers.

Separately from the Si477x-EVB kit, user's may also order an Si4770Module-A-EVB kit. The Si4770Module-A-EVB
kit consists of an Si4770 Module and Si477x Interposer card. Together, these serve in place of a daughter card on
an Si477x EVB. Alternatively, the Si4770 Module can be installed into a user-created system with a compatible
pinout. To use the Si4770Module-A-EVB in conjunction with an Si477x EVB, connect the module, interposer card,
and baseboard as shown in the figure below.
Note: The Si4770 Module is configured by default for an AM Loop Antenna connected through the Si47xx Interposer card. For
optimum results in conducted tests through the AM Test SMA connector, remove transformer T2 from the AM signal path
on the Si4770 Module.
