Overview
This EVM is configured with two RCA phono input connectors for analog input; the output signal is
available on two RCA phono connectors. The power supply is connected via a two-pin, 2,54-mm header.
This evaluation board is designed for testing applications such as set-top boxes, LCD/PDP TVs, Blu-ray
Disc™ DVD players, DVD mini-component systems, home theater-in-a-box (HTIB) systems, or
soundcards.
This document presents EVM specifications, audio performance measurements graphs, and design
documentation that includes complete circuit descriptions, schematic diagrams, a parts list, and PCB
layout design. Gerber (layout) files are available from the TI Web site at
