Using The Board (
Lab Equipment
The equipment, external supplies and signal sources
needed to operate the board are listed in the following:
Initial Board Setup Procedure
1. +2.7V to 3.6V DC Power Supply
2. Stereo Audio Source (MP3/Radio/CD Player) or Audio
3. Headphone Set or Audio Analyzer/Oscilloscope
4. Two standard High-speed USB cables
5. Computer with USB port
6. USB device (i.e. USB memory stick, MP3 Player with
1. Attach the main evaluation board to a DC power supply
2. Connect the stereo audio source left channel to J3 RCA
3. Connect the USB device to the USB “B” type receptacle,
4. Install a jumper at position 2 to 1 of JP3. This allows the

high speed USB signal. Removal of these resistors
disconnects the headphone jack (J7) and BNC
connectors (J8, J9, J14, J15) from the USB differential
lines. These components when connected will degrade
the USB signal. These components will not be there in an
actual application.
