SECTION 1 – GETTING THE EVALUATION BOARD UP AND
RUNNING
GENERAL BOARD OVERVIEW
The purpose of this section is to provide a description of the ADAV4601 evaluation board and the various ways that
this can be configured in order for the customer to fully evaluate the ADAV4601. This document describes the
various sections on the ADAV4601 evaluation board and also the ways in which data can be passed to and taken
from the ADAV4601 as well as the several ways in which the device can be clocked. Figure 1 indicates the various
sections on the evaluation board.

Figure 1: Board Description
The ADAV4601 audio processor deals with mixed signals therefore the board is divided into two separate sections,
the left side of the eval board mainly to do with the digital inputs and outputs to the part, the right side of the
board dealing mainly with the analog domain. Analog inputs and outputs are handled by way of the Phono
connectors. Figure 1 indicating the arrangement of these connectors. Digital inputs and outputs can be handled in
several ways on the eval board.
On the left side of the eval board there is a 96-way connector which can be used to interface to other evaluation
boards. It is possible to pass digital signals from another board, such as an external MCLK (for clocking the
ADAV4601) and also synchronous or asynchronous digital I2S data and framing signals. It is also possible to pass
digital signals into the ADAV4601 by way of the SPDIF connectors at the side of the evaluation board.
