MAX9539/40 Evaluation Kit
General Description
The MAX9539/40 evaluation kit (EV kit) is a fully
assembled and tested surface-mount circuit board
that contains one MAX9539 and one MAX9540 multi-
signal sync system. The MAX9539 is a video graphic
sync adder and the MAX9540 is a video graphic sync
extractor. The MAX9539/MAX9540 work together as a
chipset to provide a 3-wire (RGB) interface for 5-wire
(RGBHV) video.
The MAX9539/40 EV kit can be separated into two
individual PC boards, MAX9539 EV kit and MAX9540
EV kit. Each EV kit operates from a dual ±5V DC
power supply.

Detailed Description
The MAX9539/40 EV kit is a fully assembled and tested
surface-mount circuit board that contains one
MAX9539 and one MAX9540 in 28-pin TSSOP pack-
ages. The MAX9539 is a video graphic sync adder and
the MAX9540 is a video graphic sync extractor.
The MAX9539/40 EV kit consists of two individual EV
kits, the MAX9539 EV kit and the MAX9540 EV kit. The
two EV kits are configured on a single PCB that is break-
able along the center cutout slots. After separation, the
two EV kits can be reconnected using cables up to 20
inches long. Connect the RGB signals between the two
EV kits using equal length RG-59A/U or the RG-59B/U
BNC cables. Connect header J1 odd pins from the
MAX9539 EV kit to J2 even pins on the MAX9540 EV kit
using a Samtec IDSS-06-D-20 ribbon cable. See Table 6
for jumper locations and signal names.
The MAX9539 EV kit accepts RGBHV signals from a
5-wire interface, adds the horizontal and vertical syncs
to the RGB signals, and provides the RGB outputs with
sync to a 3-wire interface. The MAX9539 EV kit
operates from a dual ±5V DC power supply. All the
input and output signals on the MAX9539 EV kit are
DC-coupled. The MAX9539 video input terminals have
75Ω termination resistors to ground, and the output ter-
minals have 75Ω back termination (source) resistors.
The MAX9540 EV kit accepts RGB signals with sync
from a 3-wire interface, extracts the horizontal and ver-
tical syncs from the RGB signals, and provides the
RGBHV outputs to a 5-wire interface. The MAX9540 EV
kit operates from a dual ±5V DC power supply. All the
input and output signals on the MAX9540 EV kit are
DC-coupled. The MAX9540 video input terminals have
75Ω termination resistors to ground, and the output ter-
minals have 75Ω back termination (source) resistors.
The MAX9539/40 EV kit can operate as a single unit in
applications where both the graphic sync adder and
extractor can be placed on the same PCB. When the
MAX9539/40 EV kit is operated as a single unit, the
outputs of the MAX9539 must be connected to the
inputs of the MAX9540 using jumpers JU6–JU12, and
headers J1 and J2. See Table 6 for configuration.
The MAX9539/40 EV kit is fully assembled and tested.
Follow these steps to verify board operation.
Do not
turn on the power supply until all connections are
completed.
1) Verify that a shunt is installed in each of the jumper
positions in the table below:

2) Connect the output of the video graphic controller
on the desktop PC to the VGA_IN connector on the
MAX9539/40 EV kit with the VGA extension cable.
3) Connect the VGA_OUT connector on the
MAX9539/40 EV kit to the VGA input of the monitor.
4) Set both power supplies to 5V. Turn off both power
supplies.
5) Connect the negative terminal of the first power
supply to the GND pads on the EV kit and the posi-
tive terminal to the +5V pads on the EV kit.
6) Connect the negative terminal of the second power
supply to the -5V pads on the EV kit and the posi-
tive terminal to the GND pads on the EV kit.
7) Turn on the desktop PC and computer monitor.
8) Turn on both power supplies.
