Description

The ISL54210EVAL1Z evaluation board is designed to

provide a quick and easy method for evaluating the

ISL54210 USB/Audio Switch IC.

The ISL54210 device is an unique IC. To use this evaluation

board properly requires a thorough knowledge of the operation

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

functions and features of the device. Studying the device’s

truth-table along with its pinout diagram is the best way to get a

quick understanding of how the part works.

A picture of the main evaluation board is shown in Figure 2.

The ISL54210 TDFN IC is soldered onto the evaluation

board. It is located in the center of the board and is

designated as U1.

The ISL54210 IC has three modes of operation called Audio

mode, USB mode and Mute mode. The 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 these 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 an 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, configure the logic for USB

operation and then attach a USB cable from a computer to

the USB connector J1 (USB TO HOST). This will establish a

connection from the computer through the USB switches of

the IC to the USB device connected at the USB connector J2

(USB TO DEVICE), 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

ISL54210 device in both the Audio mode and the USB

mode.

Features

• Standard USB Connectors

• RCA Audio Input Jacks and Headphone Speaker Jack

• Convenient Test Points and Connections for Test

Equipment

Application Note

1-888-INTERSIL or 1-888-468-3774

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

Board Architecture/Layout

Basic Layout of Evaluation Board

• The basic layout of the main board is as follows (refer to

• The Power and Ground connections are at the top of the

• The Logic control connections are at the top of the board

• The Audio Source Inputs are at the lower right side of the

• The USB connection to an upstream host controller

• Located in the center of the board is the ISL54210 IC (U1).

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

(Computer) is made at connector J1, located on left

under-side of the board. USB connection to a downstream

USB device is made at connector J2, located on right

under-side of the board.

The evaluation board has a pin 1 dot, to show how the IC

should be oriented on to the evaluation board. The IC pin

1 indicator dot needs to be aligned with the evaluation

board pin 1 dot indicator.
