General Description
Features
The MAX9598 evaluation kit (EV kit) is an assembled
and tested printed-circuit board (PCB) used to evaluate
the MAX9598 dual SCART audio/video switch matrix. It
routes audio, video, and control signals between a set-
top box decoder chip and the VCR/TV SCART connec-
tors. The on-board microcontroller, which is connected
to the PC through the universal serial bus (USB) port,
o Windows 2000/XP/Vista (32-Bit)-Compatible
Software
o VCR/TV SCART Connectors
2
o On-Board Microcontroller to Generate I C
Commands
2
o Easy-to-Use, Menu-Driven Software
o USB-PC Connection (Cable Included)
acts as the I C master.
The EV kit also includes Windows 2000/XP/Vista®-com-
patible software that provides a simple user interface
for exercising the MAX9598 features. The program is
menu driven and offers a graphical user interface (GUI)
complete with control buttons and status displays. The
EV kit comes with the MAX9598CTL+ installed.

Search for the best driver for your device option.
Specify the location of the device driver to be
C:\Program Files\MAX9598 (default installation
directory) using the Browse button. During device
driver installation, Windows may show a warning
message indicating that the device driver Maxim
uses does not contain a digital signature. This is not
an error condition and it is safe to proceed with
installation. Refer to the USB_Driver_Help.PDF doc-
ument included with the software for additional
information.
Procedure
The MAX9598 EV kit is fully assembled and tested. Follow
the steps below to verify board operation. Caution: Do
not turn on power supplies until all connections are
made.
1) Visit www.maxim-ic.com/evkitsoftware to download
the latest version of the EV kit software, 9598Rxx.ZIP.
Save the EV kit software to a temporary folder and
uncompress the ZIP file.
15) Turn on the power supplies.
2) Install the EV kit software on your computer by run-
ning the INSTALL.EXE program inside the temporary
folder. The program files are copied and icons are
created in the Windows Start | Programs menu.
16) Start the EV kit software by opening its icon in the
Start | Programs menu. The EV kit software main
window appears, as shown in Figure 1. Observe as
the program automatically detects the address of
the MAX9598 and starts the main program.
3) Verify that all jumpers (JU1–JU7) are in their default
positions, as shown in Tables 1 and 2. Do not turn
on the power until all connections are made.
4) Connect the 12V/100mA DC power supply to the
V12 and the V12GND pads on the MAX9598 EV kit
board.

The device status registers (refer to the MAX9598 IC
data sheet for status register information) are displayed
in the MAX9598 Status group box and the Video
Activity Status group box at the bottom right of the
main window. To read the status register, press the
Read Status button, or check the Automatic Status
Read checkbox to automatically read the status regis-
ter every 250ms. The Interrupt Status group box
allows the user to detect interrupts by checking the
Interrupt Enable checkbox.

the correct I C-compatible write operation is generated
to update the internal registers of the MAX9598. The
2
Interface group box indicates the current I C-compati-
ble Device Address, Register Address Sent, and the
Data Sent/Received for the last read/write operation.
This data is used to confirm proper device operation.
The MAX9598 EV kit software splits and groups the
functions of the MAX9598 into three separate cate-
gories. TV, VCR, and Configuration functions can be
accessed by selecting the appropriate tab at the top
Press the POR Reset button to reset the MAX9598 reg-
isters and EV kit software to their power-on-reset con-
figuration.

TV Controls (Video Control)
The Video Control group box of the MAX9598 EV kit
software (Figure 1) allows the user to reroute selected
signals to the TV SCART connector. Other functions,
such as Fast Switching and Slow Switching, can
also be changed through the Video Control group
box. Manipulate the drop-down lists to achieve the
desired result.
TV Controls (Audio Control)
The Audio Control group box of the MAX9598 EV kit
software allows the user to adjust various audio charac-

Zero Crossing Detector can also be accessed from
the Audio Control group box (refer to the MAX9598 IC
data sheet for a description of each of these functions).

VCR_R/C_OUT functions can all be accessed through
the Video Control group box.
Configuration Controls
Selecting the Configuration tab sheet (Figure 3) of the
MAX9598 EV kit software allows the user to adjust con-
figuration features of the MAX9598. Checking desired
checkboxes in the Output Enable group box will
enable selected outputs of the MAX9598. The
Operating Modes group box allows the user to select
one of four power modes. A bias voltage can also be
applied at the R/C input of the encoder (Chrominance
Bias at ENC_R/C_IN). The EV kit software checks to
see if the slave is present every second. Checking the
Disable I2C Activity checkbox will stop activity
between the microcontroller and the MAX9598 when
the software is idle.

Adjust the Input Source through the Audio Control
group box of the MAX9598 EV kit software.

The MAX9598 EV kit is an assembled and tested PCB
that demonstrates the features of the MAX9598 dual
SCART audio/video switch matrix. It routes audio, video,
and control signals between a set-top box decoder chip
and the TV and VCR SCART connectors. All video con-
nections are made through 75Ω controlled-impedance
traces. Connect a TV and VCR to the corresponding
SCART connectors. The set-top box decoder video con-
nections are made through the 75Ω BNC jacks with the
ENC prefix. Audio signals from the stereo audio DAC
are connected to the white and red (P4 and P5) RCA
phono jacks. Monitor the R/C inputs of the VCR connec-
tions through the VCR_R/C_IN BNC jack.
dow or through the I C commands available by select-
ing the Options | Interface (Advanced Users) from the
menu bar. A display pops up that allows the
2
SMBus™/I C-compatible protocols, such as Read Byte
2
and Write Byte, to be executed. The only SMBus/I C-
compatible protocols used by the MAX9598 are:
•
•
1 - SMBusWriteByte(addr,cmd,data8)
4 - SMBusReadByte(addr,cmd) → data8
The combo and edit boxes accept numeric data in
hexadecimal and should be prefixed by 0x. See Figure
4 for an example of this tool.
In the example shown in Figure 4, the software is read-
ing from device address 1001011 r/w binary and regis-
ter address 0x01.
