EVM Installation
The following are the basic tools needed for the initial EVM power up.
•
Power Supply Unit (PSU) for Digital Supply (12 V)
•
PSU for PVDD (4.5 V to 26 V)
•
Banana-style test leads for power supplies
•
Optical or coaxial cable for SPDIF interface based on signal source
•
USB cable
•
EVM Software
•
Speaker or loads for outputs
The following sections describe the EVM board in regards to power supplies (PSU) and system interfaces.
2.1.1
Connecting the EVM to the Input-USB Board3
On the right side of the Input-USB Board3 is a terminal block and another is located on the left of the EVM
(labeled J1). Carefully place the Input-USB Board3 block above the EVM block and gently push down.

2.1.2
Power Supply Interface
The EVM is powered by two PSUs connected to the Input-USB Board3 controller board: a 12-V PSU (V
IN
),
and a 4.5- to 26-V PVDD PSU. The 3.3- and 5.0-V levels are generated on the board by voltage
regulators from the 12-V supply.
