Description

The ISL54207EVAL1Z evaluation board is designed to

provide a quick and easy method for evaluating the

ISL54207 USB/CVBS/Audio IC.

The ISL54207 device is an unique IC. To use this evaluation

board properly, requires a thorough knowledge of the

operation of the IC. Refer to the ISL54207 datasheet 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 ISL54207 datasheet, 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 ISL54207 µTQFN IC is soldered onto the evaluation

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

designated as U1.

The ISL54207 IC is a dual SPDT analog switch that was

designed to multiplex between mono audio/video (A/V)

signals or USB differential signals of a portable media player

such as digital cameras, camcorders, MP3 players and

cellphones.

The part has two modes of operation: Audio/Video mode and

USB mode. The evaluation board contains standard RCA,

BNC, and USB connectors to allow the user to easily

interface with the IC to evaluate its functions, features, and

performance in these two modes of operation.

For example, when the board is properly powered, the

video/mono audio outputs of a video MP3 player can be

connected at RCA connectors J13 (VIDEO IN) and J15

(MONO AUDIO IN) and the USB output of the player can be

connected at the USB connector J12 (USB TO DEVICE) on

the board. See Figure 2 on page 4. A TV can be connected

at RCA jacks J5 (VIDEO OUT) and J7 (MONO AUDIO OUT)

to play the video on the TV. You can then turn-off the video,

disconnected the TV, and attach a USB cable from a

computer to USB connector J4 (USB TO HOST) to load

digital video tracks into the player.

This application note will guide the user through the process

of configuring and using the evaluation board to evaluate the

ISL54207 device in both the Audio/Video mode and the USB

mode.

Key Features

• Standard USB Connectors

• RCA Audio/Video Input Jacks and BNC Connectors

• Convenient Test Points and Connections for Test

Equipment

Application Note

ISL54207EVAL1Z Evaluation Board User’s

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

Figure 1.

Power (J2), GND (J1), logic VBUS (J3) and logic CTRL (J11)

banana jack connections are at the top of the board.

Audio/Video Source RCA inputs are at the lower right side of

the board (J13 and J15). Audio/Video RCA outputs are at

the lower left side of the board (J5 and J7).

A standard “B” type USB connection to an upstream host

controller (Computer) is made at connector J4, located on

left underside of the board. A standard “A” type USB

connection to a downstream USB device is made at

connector J12, located on right underside of the board.

Located in the center of the board is the ISL54207 IC (U1).

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

Note: The connectors J5 (VIDEO OUT) and J7 (MONO

AUDIO OUT) are connected in parallel to J4 (USB TO

HOST). When driving the USB input, the A/V output should

be in a high impedance state (and vice versa).
