Microcontroller and Associated Peripherals The Si4700/01/02/03 evaluation board uses a Silicon Laboratories' C8051F320 microcontroller to control the Si4700/01/02/03 and to provide USB connectivity to the EVB (via J1). The LED D1 blinks to confirm that power is being properly supplied to the C8051F320 and the MCU firmware has loaded. Push-button PB1 manually resets the C8051F320. The JTAG connector J2 is used to program the C8051F320 at production time, and is not necessary for normal operation. J2 can be used for downloading example code or updating the MCU firmware. See www.mysilabs.com for details. 3.1.2. Reference Clock for the Si4700/01/02/03 The Si4700/01/02/03 accepts a 32.768 kHz reference clock input at the RCLK pin. On the baseboard, this clock is provided by a precision crystal oscillator. The output of the oscillator is routed to the Si4700/01/02/03 RCLK pin through a Schmitt-trigger buffer (U5) and a 33 series termination resistor (R19). The user has the option of not using the oscillator and bringing in the reference clock from an external source through J6. This can be achieved by depopulating R19 and populating R21 with a 0 resistor as shown in Table 1. Note that the reference clock is not routed through the Schmitt-trigger buffer when an external clock source is being used. A third option is available which takes advantage of the Si4700/01/02/03 internal oscillator. This can be achieved by depopulating R2 and R3 on the bottom of the daughter card. 3.1.3. Power Supply Network For additional flexibility in usage and testing, the baseboard can accept power from up to 3 independent power supplies via connector J4. When connecting one or more power supplies to connector J4, care must be taken not to supply power via J1 (USB POWER) or J7 (EXT POWER). When connecting more than one power supply to connector J4, care must be taken to configure R1, R2, and R4. See the Figure 2 for reference. J4 provides flexibility for varying the 3 separate supplies on the board: VRADIO, VAUDIO, and VIO/VMCU. VRADIO is applied to the VA and VD pins of the Si4700/01/02/03, VAUDIO powers the audio amplifier network, and VIO/VMCU powers the baseboard microcontroller, the reference clock system, and VIO on the Si4700/01/02/03. Prior to using J4 it is necessary to remove R1, R2, and R4 as these resistors short the three connections on J4 together. When supplying VIO/VMCU via the J4 connector, a supply > 5 V may be used in conjunction with the 3.3 V LDO regulator U2. However, U2 may be bypassed by depopulating U2 and populating R30 with a 0 resistor. In this case, the VMCU/VIO supply at J4 must lie between 3.0 and 3.6 V. This condition is necessary to ensure reliable operation of the C8051F320. When supplying VRADIO via the J4 connector, a supply > 5 V may be used in conjunction with the 3.3 V LDO regulator U3. However, U3 may be bypassed by depopulating R14 and populating R25 with a 0 resistor. In such a case, the VRADIO supply at J4 must lie between 2.7 and 5.5 V. These are the recommended operating conditions for the Si4700/01/02/03. When the EVB is used in its simplest configuration, SW1 can be set to USB POWER and powered via the USB connector, J1, or to EXT POWER and powered via the ac connector J7 and included transformer. No additional configuration is required beyond selecting the position of SW1. J7 is a 2.1 mm power jack for use with standard transformer power bricks. The power brick must be dc and provide at least 5 V on the inner conductor. The regulators on the baseboard are capable of handling up to 26 V, so most dc power bricks are acceptable. To power the board via J7, SW1 must be in the EXT POWER position and no power should be applied via J4. This configuration is convenient when using the JTAG header to program custom code into the C8051F320.

Expansion I/O connector 3.2.2. Audio Amplifier The 20-pin Expansion I/O connector J3 provides access to all the control signals of the Si4700/01/02/03 including the general purpose input/output pins. Pins for the VA, VD, VIO, and RCLK pins of the Si4700/01/02/03 are also available. All test points on J3 are labeled indicating the signal available at the pin. The daughter card includes a high-output drive dual opamp chip (U2—daughter card) to buffer the audio outputs at the LOUT and ROUT pins of the Si4700/01/02/03. The LOUT and ROUT pins are also ac-coupled to the inputs of the op-amps on U4 daughter card. To drive the headphone jack, the opamps are connected in a unity-gain, noninverting configuration and biased at the middle of the audio power supply. The outputs of the U2 op-amps are in turn ac-coupled to the BNC connectors J10 and J11 on the baseboard. Note: The unlabeled pins on J3 between (a) SCLK and RST, and (b) RCLK and GPIO1, provide access to the system ground. 3.2. Si4700/01/02/03 Daughter Card 3.2.1. Si4700/01/02/03 FM Tuner Chip The Si4700/01/02/03 (U1) and its bypass capacitors* are located on the daughter card. The Si4700/01/02/03 is configured to accept a single-ended FM input—the FMIN pin is grounded and the FMIP pin is connected to J1 through an ac-coupling capacitor. FMIP is also connected to the ground wire of the headphone jack (J3) for easy testing of a headphone wire as the antenna. Refer to “AN231: Si4700/01 Headphone and Antenna Interface” for more information. *Note: We recommend a single bypass capacitor on VD. To account for various supply designs and layouts, we recommend that customers make provisions for bypass capacitors at all supply pins. 6 The audio amplification network has been designed to drive resistances of 10 k which is easily achievable on most audio analyzers. The op-amps have enough drive capability to drive resistances much lower than 10 k (e.g. 32 headphones). In such cases, however, the lower end of the audio spectrum (up to 2.5 kHz) will be attenuated. This is because the 3-dB points of the highpass filters at the outputs of the op-amps move to higher frequencies as the output resistance is decreased. Also note that the op-amps are not protected against extended short-circuit conditions. Hence, the audio outputs at J10 and J11 should not be connected to a mono input if the Si4700/01/02/03 is configured to produce a stereo output. Rev. 0.9 Si4700/01/02/03-EVB 4.

Log Band Scan Selecting ToolsLog 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 ViewSession PreferencesScan 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 ViewSession PreferencesScan 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 ToolsLog 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. 6.2.7. Log Raw RDS Data Selecting ToolsLog 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 ToolsLog 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. 6.2.8. Log Channel Info Selecting ToolsLog 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 ToolsLog Channel Info is selected a second time, at which point the file is saved and available for analysis in a text editor or spreadsheet. 6.2.9. Log Device Commands Selecting ToolsLog 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 ToolsLog Device Commands is selected a second time, at which point the file is saved and available for analysis in a text editor. 6.2.10.

GUI Properties (Continued) Property RDS ERROR CHECKING Description RDS Error Checking Settings Three options are available: Minimum - displays the RDS data exactly as it is received from the Si4701/03. Mid-level - RDS data is verified by comparing the current byte with the previous bytes received from the Si4701/03. Only consistent data is displayed. If the A/B flag toggles, the data is displayed regardless of verification status. Data is more error free than the minimum setting, but some errors may be displayed on stations using the A/B flag improperly. Maximum - RDS data is verified as in the mid-level setting, but the A/B flag is ignored. Data is virtually error free, but may take longer to display.
