Description

The ISL54214EVAL1Z and ISL54217EVAL1Z evaluation

boards are designed to provide a quick and easy method for

evaluating the ISL54214 and ISL54217 USB 2.0

High Speed x 2 Channels/Stereo Audio Dual SP3T (dual

3-to-1 Multiplexer) Switch ICs.

To get an evaluation board with an ISL54214 IC, order P/N:

ISL54214EVAL1Z. To get an evaluation board with ISL54217

IC, order P/N: ISL54217EVAL1Z

The ISL54214 and ISL54217 devices are unique ICs. To use

the evaluation board properly requires a thorough

knowledge of the operation of the ICs. Refer to the data

sheets for an understanding of the functions and features of

these devices. Studying the device’s truth-table along with its

pinout diagram in the ISL54214 and ISL54217 data sheets 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 ISL54214 or ISL54217 TQFN IC is soldered onto the

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

is designated as U1.

The ISL54214 or ISL54217 IC has five states or modes of

operation called ALL OFF, USB1, USB2, Audio and Audio

Mute. 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

five modes of operation.

For example, when the board is properly powered, a

headphone can be plugged into the headphone jack, (J20)

and a stereo

connected at the RCA connectors J16 (AUDIO LEFT) and

J18 (AUDIO RIGHT). The S2 and S1 toggle switches on the

board can be put into the High position 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 USB1 operation (S1 = Low, S2 = High) and then

attach a USB cable from a computer to the USB connector

J15 (USB TO HOST). This will establish a connection from

the computer through the USB1 switches of the IC to the

USB device connected at the USB1 connector J13 (USB TO

DEVICE 1), 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

ISL54214 or ISL54217 device in the five modes of operation.
