MAX9979 Evaluation Kit
Quick Start
Required Equipment
Before beginning, the following equipment is needed:
•
MAX9979 EV kit (USB cable included)
•
•
•
•
•
•
A user-supplied Windows 2000/XP- or Windows
Vista-compatible PC with a spare USB port
+17.5V/0.5A DC power supply (VHH)
-4.75V/0.5A DC power supply (VEE)
Differential output pulse generator
High-speed oscilloscope
Digital multimeter
9)
8)
Connect the digital multimeter positive input to
TP10, and the negative input to ground. Ensure
that the multimeter is in DC-voltage measurement
mode, either on auto range or a fixed range
greater than 5V.
Connect the differential pulse generator to the
DATA0 and NDATA0 SMA connectors on the
MAX9979 EV kit with SMA cables of equal length.
Evaluates: MAX9979
10) Set the RCV0/NRCV0 to a differential logic-low
(i.e., V
RCV0
< V
NRCV0
) to disable the high-imped-
ance output mode.
11) Connect the OUT0 SMA connector of the
MAX9979 EV kit with a short SMA cable to the
high-speed oscilloscope. Set the scope input
impedance to 50Ω.
12) Turn on the power supplies in the following order:
VHH, VEE.
13) Enable the differential pulse generator.
14) Connect the USB cable from the PC to the EV kit
board. A
New Hardware Found
window pops up
when installing the USB driver for the first time. If a
window that is similar to the one described above
is not seen after 30s, remove the USB cable from
the board and reconnect it. Administrator privi-
leges are required to install the USB device driver
on Windows.
15) Follow the directions of the
Add New Hardware
Wizard
to install the USB device driver. Choose
the
Search for the best driver for your device
option. Specify the location of the device driver to
be
C:\Program Files\MAX9979
(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
document included with the software for additional
information.
16) Start the MAX9979 EV kit software by opening its
icon in the
Start | Programs
menu. The EV kit soft-
ware main window appears, as shown in Figure 1.
17) Put the EV kit into drive mode by checking the
DriveHi Ch0/Ch1 quickstart
checkbox on the
DCL/Channel 0
tab sheet of the GUI, as shown in
Figure 2. This is a quick start option and places
both channel 0 and channel 1 into the drive-high
mode. In this mode, VDH is set to 3V and VDL to
0V for both channels.
Note:
In the following sections, software-related items
are identified by bolding. Text in
bold
refers to items
directly from the EV kit software. Text in
bold and under-
lined
refers to items from the Windows operating system.
Procedure
The MAX9979 EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supplies until all
connections are completed.
1)
Visit www.maxim-ic.com/evkitsoftware to download
the latest version of the EV kit software,
9979Rxx.ZIP. Save the EV kit software to a tempo-
rary folder and uncompress the ZIP file.
Install the EV kit software on your computer by run-
ning the INSTALL.EXE program inside the tempo-
rary folder. The program files are copied and icons
are created in the Windows
Start | Programs
menu.
Make sure the shunts of all jumpers are in the
default positions, as shown in Tables 2 and 3.
Verify that the heatsink is installed and flush on the
top of the MAX9979 IC.
Verify the correct polarity, voltage, and current limit
of all power supplies. Ensure all power supplies
are disabled (at 0V).
Set the differential pulse generator to output
±100mV centered at +1.2V common-mode volt-
age. Ensure that the outputs are disabled (high
impedance). Set the pulse frequency to 20MHz,
50% duty cycle.
Connect the power supplies to the banana jacks of
the MAX9979 EV kit. Connect all power-supply
grounds to a single ground terminal.

18) TP10 monitors the MAX9979 junction temperature.
Verify that the multimeter does not read higher
than +4.2V (T
J
< +150°C).
19) Set the oscilloscope to 50Ω input-impedance mode.
20) Set the oscilloscope to trigger on the OUT0 chan-
nel, with the trigger level set to 0.5V. Set the time
base to 20ns per division. A 0 to 3V square wave
of 20MHz should appear on the oscilloscope.
Detailed Description of Software
User-Interface Panel
The GUI is organized into four tab sheets for all level,
register, and control signal settings, plus the
File
menu
to save and load all these settings. There are identical
DCL and PMU/Control tab sheets for channels 0 and 1,
respectively.

DCL/Channel 0
and

tab sheets
(Figures 1 and 3) are identical and are for channels 0
and 1, respectively. These tab sheets contain
Level

group boxes.
Level Settings
The
Level Settings
group box contains registers for
signal level, calibration, and gain settings for VDH,
VDL, VDT, VCH, VCL, VCPH, VCPL, VCOM, VLDH, and
VLDL level settings. Each setting is controlled by a
scrollbar with a value label to its right. Finer adjustment
can be made by clicking on the arrows on each side of
the scrollbar. The scrollbars in the
Level
group box
have 65,536 steps corresponding to 16 bits. In the
Calibration
group box, the
Offset
scrollbars have 256
steps corresponding to 8 bits, and the
Gain
scrollbars
have 64 steps corresponding to 6 bits. The correspond-
ing voltage levels are also calculated and shown in the
edit boxes inside the
Voltage
group box. The value,
calibration, and gain selections become effective
immediately after an adjustment without having to press
