Instructions for Si473x daughtercards.
1. Connect the USB cable from PC to the EVB USB connector, J79. The USB connection will not only allow controlling of the
EVB, but will also provide power to the EVB.
2. Connect either the ferrite antenna or the airloop antenna board. The user also has the option of using the AM test input for
characterization by connecting the AM test input connector J1 to an RF generator source.
3. Connect an audio analyzer to the RCA output (connector J6) using an RCA cable for the analog audio output.
4. Connect an audio analyzer to the S/PDIF output (connector J30) using an optical cable.
5. Or, connect the headphone output to J24 on the daughtercard.
6. J19 and J30 S/PDIF connections are no longer supported on EVBs as of February 14, 2011.
