This section describes the EVM and software installation.
2.1 EVM Installation
Figure 3. General Connection Picture
The following are the basic tools for the initial EVM power up.
• 5V, 1A power supply (VIN)
• 8–26V, 4A power supply (PVDD)
• Banana-plug test leads for power supplies and speakers
• Optical or coaxial cable for SPDIF interface based on signal source
• USB cable
• EVM software
• Two 8Ω speakers or loads
The following sections describe the TAS5715EVM board in regards to power supply (PSU) and system
interfaces.
2.1.1 Connecting the TAS5715EVM to MC57xxPSIA
On the right side of the MC57xxPSIA is a terminal block and another on the left of the TAS5715EVM
(labeled J1). Carefully place the MC57xxPSIA block above the TAS5715EVM block and gently push down.
