Instructions for Si474x daughtercards:
1. Connect the USB cable from PC to the EVB USB connector, J79. The USB connection will serve two purposes: supplying
the power to the EVB and controlling the EVB.
2. Connect a whip antenna to J4. The user has the option of using the AM test input for characterization by connecting the AM
test input connector J4 to an RF generator source through an antenna dummy.
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. J19 and J30 S/PDIF connections are no longer supported on EVBs as of February 14, 2011.
