Lab Equipment
The equipment, external supplies and signal sources
needed to operate the board are listed in the following:
Initial Board Setup Procedure
1. +3V to 5V DC Power Supplies
2. Stereo Audio Source (MP3/Radio/CD Player) or Audio
3. Headphone Set or Audio Analyzer/Oscilloscope
4. Standard USB High-Speed Cables
5. Computer with USB Port
6. Two USB Devices (i.e. USB Memory Stick, MP3 Player
1. Attach the main evaluation board to a DC power supply
2. Connect a DC power supply at J5 (VBUSCH1) and J2
Generator
with USB Port, etc.)
at J1 (VDD) and J2 (GND). Positive terminal at J1 and
negative terminal at J2. The supply should be capable of
delivering 3V to 5V and 100mA of current. Set the supply
voltage to 3.3V.
(GND) (positive terminal at J5 and negative terminal at
J2). The supply should be capable of delivering 5V and
100mA of current. Set the supply voltage to 5V. This
supply provides the required V
