Description

The ISL5440XEVAL1Z evaluation board is designed to

provide a quick and easy method for evaluating the

ISL54400, ISL54401 and ISL54402 USB/Audio Switch ICs.

An evaluation kit consists of the following items: One Main

Evaluation Board; Three

with mounted IC; ISL5440XEVAL1Z Evaluation Board User’s

Manual; ISL54400, ISL54401, ISL54402 Data Sheet; Main

Evaluation Board Schematic.

The ISL54400EVAL1Z kit contains three daughter boards

with the ISL54400 part.

The ISL54401EVAL1Z kit contains three daughter boards

with the ISL54401 part.

The ISL54402EVAL1Z kit contains three daughter boards

with the ISL54402 part.

The ISL5440x devices are unique ICs. To use this evaluation

platform properly requires thorough knowledge of the operation

of the ICs. Refer to the data sheet for an understanding of the

functions and features of this family of devices. Studying a

device’s truth-table along with its pinout diagram on pages 2

and 3 of the data sheet is the best way to get a quick

understanding of how a particular part in this family works.

A picture of the main evaluation board with IC to dip daughter

board installed is shown in Figure 1. The main board has a 10

pin dip socket (U1) located in the center of the board. An IC is

soldered onto a 10 pin dip daughter board that is plugged into

the dip socket on the main board. Using daughter boards

allow for the easy installation and removal of ICs.

The USB/Audio Switch ICs have two modes of operation

called Audio mode and USB mode. The main evaluation

board contains standard Audio and USB connectors to allow

the user to easily interface with the IC to evaluate its

functions, features, and performance in the two modes of

operation. For example, when the board is properly

powered, a headphone can be plugged into the headphone

jack (J7) and a stereo source, such as a MP3 player, can be

connected at the RCA connectors J3 (AUDIO LEFT) and J4

(AUDIO RIGHT) to play music through the audio switches of

the IC. See Figure 2. You can then turn-off the audio source,

remove the headphones, and attach a USB cable from a

computer to USB connector J1. This will establish a

connection from the computer through the USB switches of

the IC to the USB device, that is connected at the USB

connector J2, to send and receive data.

This application note will guide the user through the process

of configuring and using the evaluation board to evaluate the

ISL5440x family of devices in both the Audio mode and the

USB mode.

Board Architecture/Layout

Basic Layout of Main Board

The basic layout of the main board is as follows: Refer to

Figure 1.

Power and Ground connections are at the top of the board

(J10 and J11).

Audio Source Inputs are at the lower right side of the board

(J3 - J6). Audio outputs are at the lower left side of the board

(J7, J8, J9). Connector J7 is a standard headphone jack for

connecting a 32

USB connection to an upstream host controller (Computer)

is made at connector J1, located on left under-side of the

main board. USB connection to a downstream USB device is

made at connector J2, located on right under-side of the

main board.
