27 4. Hardware Overview The Si46xx EVB platform uses a baseboard and daughtercard system to allow the easy evaluation of different members of the Si46xx product family. The baseboard PCB provides power, a host controller, USB communication, audio output, test connections, and connectors to accommodate daughtercard connections. The daughtercard features an installed tuner IC, RF front-end circuitry, and an antenna/signal generator connector Digital Radio Baseboard Figure 29. Digital Radio Baseboard Features The digital radio baseboard offers several features that can be used to interface with and evaluate the performance of all of the Si46xx family of products. For detailed information, please see the provided baseboard schematic. 1. Daughtercard Connector Connect the Si46xx daughtercard here. 2. Audio Output Jacks Two audio outputs are provided and are labeled on the PCB. One is the lineout directly from the tuner's analog audio output DACs. The other is lineout audio, but is a headphone amplifier buffered output. 3. USB Connector Connect the baseboard's host controller to a PCB to interface with the Silicon Labs GUI and optionally provide power to the EVB platform. 4. Test Point Connections Provides easy access to Si46xx signals. 5. Power Selection Switch Use this switch to select the baseboard power source (USB power or external power from connection at (7) or header J76). This allows the use of a 6 to 12 V supply (e.g., a 9 V battery or wall adapter supply). Mid-position of the switch is OFF as labeled on the PCB. The selected EVB power supplies both the host MCU and the voltage regulators that may supply the Si46xx tuner IC. 6. Terminal Block Power Connections Allow the use of external lab bench power supplies for VA, VIO, VCORE, and VMEM. Use of the terminal blocks must be selected using selection jumpers (8). 7. External Power Supply Connector Used to connect to 6 to 12 V power supply to provide power to the EVB. 8. Tuner/Daughtercard Power Supplies Provides VA, VCORE, VMEM, and VIO power supplies to the Rev

28 tuner. (See section Tuner Power Supply Options for more details). 9. Current Supply Measurement Headers J24, 28, 34, and 39 provide an easy means of measuring current consumption (see section Tuner Power Supply Options for more details) Tuner Power Supply Options The baseboard offers a convenient power supply system to accommodate various supply voltages and options and provides a means of easily evaluating the tuner with different voltage supply configurations. Four different voltage supplies, VA, VIO, VCORE, and VMEM, are provided as shown in the schematic in Figure 30. The user may change resistors in the voltage regulators' feedback circuits in order to obtain different supply voltages. The baseboard also supports the use of external lab power supplies via terminal block connectors J87 (VA and VIO) and J94 (VCORE and VMEM). To use external bench power supplies, solder from jumpers J57, J58, J67, and J68 must be removed. This allows the use of jumpers J60, J61, J72, and J78 to select the use of the terminal blocks or the on-board voltage regulators. See the full schematic for details. The EVB also provides an easy interface for measuring supply current to the tuner itself. In-line current measurement may be performed using headers J24, J29, J35, and J39 near the center of the baseboard (see Figure 30). In order to measure current, solder must be removed from jumpers J25, J30, J36, and J40. Figure 30. Tuner Power Supply Schematic 28 Rev. 0.6

29 Si46xx Daughtercard The EVB platform may accommodate several different daughtercards in order to allow evaluation of several different tuners using the same baseboard. Signals routed to the baseboard connector may be disconnected by removing in-series 0 resistors. Figure 31. Si46xx QFN Daughtercard 1. RF Input (SMA) and RF Front-end Input Circuit The daughtercard is configured for fast and easy evaluation. Simply connect an antenna or signal generator to the provided SMA connector. 2. Crystal Oscillator For convenience, the daughtercard is shipped with a 19.2 MHz crystal oscillator installed on the PCB. 3. Receiver IC Installed Si462x Data Receiver. Rev

31 6. Errata 6.1. Windows PC Sleep Mode May Place the GUI in an Unresponsive State Issue: If the PC goes to a sleep mode while the GUI is in operation, the GUI may become unresponsive and lose communication with the EVB. Workaround: If this occurs, restart the PC I 2 C Glitch after ACK Issue: Due to an EVB hardware issue (and not a si46xx issue) a glitch may be observed on the falling edge of an I 2 C ACK on the SDA data signal. Workaround: This issue does not affect I 2 C communication and so no workaround is recommended. This issue is documented for informational purposes GUI Presents Incomplete Service Info after Reconfiguration Issue: 4680 GUI does not handle service list update after the reconfiguration interrupt is fired. As a result, partial service list update could be observed if such event happens. Click on the service (manually triggering another service list update) will resolve this issue. Rev
