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.
2) 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.
3) Make sure the shunts of all jumpers are in the
default positions, as shown in Tables 2 and 3.
4) Verify that the heatsink is installed and flush on the
top of the MAX9979 IC.
5) Verify the correct polarity, voltage, and current limit
of all power supplies. Ensure all power supplies
are disabled (at 0V).
6) 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.
7) Connect the power supplies to the banana jacks of
the MAX9979 EV kit. Connect all power-supply
grounds to a single ground terminal.
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.
9) Connect the differential pulse generator to the
DATA0 and NDATA0 SMA connectors on the
MAX9979 EV kit with SMA cables of equal length.
10) Set the RCV0/NRCV0 to a differential logic-low
(i.e., VRCV0 < VNRCV0) 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.

18) TP10 monitors the MAX9979 junction temperature.
Verify that the multimeter does not read higher
than +4.2V (TJ< +150°C).
19) Set the oscilloscope to 50Ωinput-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.

Figures 1, 3, 4, and 5. The second is through the
Advanced User Interface window shown in Figure 6.
The Advanced User Interface window is available by
selecting the Option | Interface (Advanced User) menu
item and allows execution of serial commands manually.
The Advanced User Interface window can also be
used as a debug tool because it is capable of manually
reading and writing to every register of the MAX9979.
Detailed Description of Hardware
The MAX9979 evaluation kit (EV kit) is a fully assembled
and tested PCB that evaluates the MAX9979 dual PEIC
with PMU. The EV kit includes SMA connections for the
high-speed digital I/Os and the MAX9979 pin driver
outputs. The MAX9979 EV kit is connected to the com-
puter through the universal serial bus (USB) port.
Power Supplies
Connect the power supplies using the high-current
banana jacks, J22 (-4.75V) and J23 (17.5V). Common
for all the power supplies should be the GND banana
jack on the MAX9979 EV kit. All power supplies should
be within the range specified in the MAX9979 IC data
sheet. The MAX9979 needs only two supplies to be
attached to the board; all other supplies are generated
through regulators on the EV kit board.

High-Speed Digital I/Os
The top edge and the bottom edge of the PCB are pop-
ulated with end-launch SMA connectors, and are the
high-speed digital I/Os of the MAX9979. The inputs are
terminated internally to the MAX9979 IC. The outputs
require termination (nominally 50Ω) at the end of the
attached cable.
The board power supply (VTRM) is the voltage used to
terminate the comparator outputs on the MAX9979 IC.
Setting VTRM to +1.2V makes the high-speed digital
I/Os compatible with LVDS levels.
The high-speed digital inputs (DATA0/NDATA0,
RCV0/NRCV0, DATA1/NDATA1, and RCV1/NRCV1) are
intended for use with a high-speed differential signal
source such as LVDS, LVPECL, ECL, etc. If only a single-
ended stimulus source is available, a converter consist-
ing of a 1:1 ratio transformer (balun) can be used to
produce a differential pair of inputs for DATA0/NDATA0
or DATA1/NDATA1. A three-resistor network can be
used to produce a differential logic level for
RCV0/NRCV0 or RCV1/NRCV1 inputs.
The high-speed digital outputs (CL0/NCL0, CH0/NCH0,
CL1/NCL1, and CH1/NCH1) are intended for use with a
high-speed differential logic analyzer. These outputs are
internally pulled up to the VTRM voltage through internal
50Ωresistors. These outputs can be double terminated
at the measurement source by external 50Ωresistors.
Pin Driver Outputs
The dual-pin driver outputs or DCLP IO pins (DUT0 and
DUT1) are through end-launch SMA connectors on the
right edge of the PCB. The outputs have a typical output
impedance of 50Ω, which can be adjusted by software.
Test Points
There are 23 test points on the EV kit to facilitate perfor-
mance analysis and circuit modification. The test points
are listed in Table 1.

Device Ground Sense
The MAX9979 IC has the ability to sense the ground
potential at the device under test (DUT). The MAX9979
EV kit is preconfigured to have the device ground
sense pin (DGS) connected to the ground plane
through a 0Ωresistor (R9). If remote sensing is desired,
remove R9 and connect TP5 to the remote DUT ground.
Temperature Sensing
The MAX9979 EV kit provides the means to determine
the MAX9979 IC’s die temperature through TP10.
During operation, TP10 should be continuously moni-
tored to ensure that the junction temperature does not
exceed +150°C, which corresponds with +4.2V. During
normal operation, a voltage of 3V to 3.6V is typical.
