Description

The ISL54209EVAL1Z evaluation board is designed to

provide a quick and easy method for evaluating the

ISL54209 USB/Audio Switch IC.

The ISL54209 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 on page 2 of the ISL54209 data sheet 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 1.

The ISL54209 TDFN IC is soldered onto the evaluation

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

designated as U1.

The ISL54209 IC has two modes of operation called Audio

mode and USB 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 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

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

RIGHT) to play music through the audio switches of the IC

(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

ISL54209 device in both the Audio mode and the USB

mode.

under-side of the board. USB connection to a

downstream USB device is made at connector J2,

located on right underside of the board.

the IC should be oriented onto the evaluation board. The

IC pin 1 indicator dot needs to be aligned with the

evaluation board pin 1 dot indicator.
