MAX3845/MAX4814E Evaluation Kit
For evaluation of the MAX3845 and MAX4814E, configure the board as follows:
1) Ensure that jumpers are placed on JU1 and JU2 to
allow use of the wall-plug power supply. Shunt the
bottom two pins of JU3 to allow direct control of the
MAX4814E using BCD switches S9 and S10.
2) Plug the power supply into the 120V AC socket and
plug the other end into J9. The output LEDs should
light up. The Clock Loss LED (D11) should light up
red if the MAX3815 is powered (SW20 switch set to
the ON position).
3) Since the board has back termination resistors
installed on the board by default, set the OUTPUT
LEVEL switch (SW13) to HIGH. This sets the output
swing to the normal HDMI/DVI range even with the
back termination resistors in place.
4) Connect DVI/HDMI sources and sinks to the inputs
and outputs on the EV kit. The LEDs turn green when
a powered device is connected to the outputs. This
is done by detecting the +5V signal at HOTPLUG.
Note: The DVI connectors on the board allow singlelink and dual-link DVI cables with DVI-D (digital only)
and DVI-I (digital and analog) connectors, but only
digital single-link video passes through the board.
5) If a long DVI cable is used to connect to a source,
connect it to INPUT 2. This input has the MAX3815
equalizer on it to compensate for high-frequency
losses on long cables.
6) If a source is connected to INPUT 2, be sure to
power up the MAX3815 by switching SW20 to ON
and SW19 to AUTO.
7) Route the DDC signals through the board using the
S9 and S10 rotary switches. Switch S9 routes the
DDC signals from input 1, and switch S10 routes
the DDC signals from input 2.
Note: INPUT 1 DDC has priority, so if INPUT 1 and
INPUT 2 are connected to the same output, the
DDC connections from INPUT 2 are opened.
8) Select the input that you want to appear at outputs
1 to 4 by using the input select switches (S2, S4,
S5, S7).
9) Select the amount of preemphasis (0dB, 3dB, 6dB)
you want to appear at each output using the preemphasis switches (S1, S3, S6, S8).
If manual control of the MAX3815 equalizer is desired,
switch SW19 to MANUAL. To increase the amount of
equalization (long cables), turn R50 clockwise. To
decrease the amount of equalization (short cables),
turn R50 counterclockwise. Note that during manual
equalization, all three TMDS data channels are set to
the same level of equalization.
ESD Protection
The MAX3845 provides 2kV of ESD protection on all
pins. If a higher level of ESD protection is desired, the
MAX3208E provides 15kV of ESD protection for DVI
and HDMI interfaces. It is designed to provide protection for differential lines while maintaining a low capacitance for minimal effects on signal transmission.
Twelve MAX3208E devices are included in this
EV kit to protect all TMDS I/O connections. For samples, contact the Maxim Samples Department at
www.maxim-ic.com/samples or call (888) 629-4642.

COMPONENT
NAME
FUNCTION
JU3
MODE
Short the bottom two pins of JU3 to control the MAX4814E using the rotary switches S9 and
S10. Short the top two pins to control the MAX4814E through I2C using TP8 (SDA) and TP9
(SCL).
R50
EQ ADJ
S1, S3, S6, S8
PREEMPHASIS
These switches are used to set the level of preemphasis on the MAX3845’s output drivers
(0dB, 3dB, or 6dB).
S2, S4, S5, S7
INPUT SELECT
These switches are used to select which input signal appears for each output. The middle
position powers down the output.
S9, S10
DDC
SWITCHING
These rotary switches are used to connect the DDC signals (SDA, SCL, HOTPLUG, and
+5V) from one input to one output.
SW1–SW4
HOTPLUG
DETECTION
These switches allow the HOTPLUG signals from the DVI sinks to power up and power
down the MAX3845 outputs. To force operation of an output regardless of the HOTPLUG
signal, slide the switch down.
SW13
OUTPUT LEVEL
This switch sets all the MAX3845’s outputs to increased current drive (HIGH) or normal
current drive (LOW). The increased current drive setting allows for 200 back termination
resistors to be used (installed as default on the board).
SW14
POWER DOWN
This switch powers down input 1 when slid down. Note that any output selected to that
input would be powered down as well. The PWRDWN_2 pin is controlled by the loss-ofclock circuit on the MAX3815. If the MAX3815 detects a signal at its RXC_IN input, it
powers up input 2 of the MAX3845. If no clock signal is detected, it powers down input 2.
SW19
EQ MODE
Slide the switch up to manually control the level of equalization of the MAX3815. Slide it
down to have the MAX3815 automatically control the level of equalization.
SW20
MAX3815
POWER DOWN
TP2
TEMP SENSE
TP8
SDA
TP9
SCL
When manual control of the equalizer has been selected using SW19, the level of
equalization on the MAX3815 is controlled by R50.
This switch powers down the MAX3815 when slid down.
When the MAX3845 is powered up, the die junction temperature can be estimated by
measuring the voltage on TP2 relative to GND. For more information, refer to the MAX3845
data sheet.
Connect an I2C source to TP8 (SDA) and TP9 (SCL) to control the MAX4814E.
