MAX3814 Evaluation Kit
The MAX3814 evaluation kit (EV kit) simplifies evaluation of the MAX3814 TMDS equalizer/driver. This EV kit
allows for quick testing of the MAX3814 with either a
DVI or HDMI environment. The MAX3814 EV kit is fully
assembled and tested.

DESCRIPTION
MAX3814 DVI/HDMI+ Equalizer
Rev A Evaluation Board
Features
♦ Fully Assembled and Tested
♦ Includes AC-Powered Battery Eliminator
Quick Start
1) Connect the “wall plug power supply (U7)” to the
power jack J3. Jumper JU3 to connect the board
supply to the wall plug supply (WWART).
2) For DVI use, connect the input cable/board to the
DVI input and connect a DVI monitor or DVI receiver to the MAX3814 EV kit output. Change jumper
JU1 to enable DVI equalizer. Jumper JU2 can
remain disabled. The default setting is LEVEL = 1
with 200Ω back terminations.
3) For HDMI use, connect the cable or board to the
HDMI input and connect a monitor or receiver to
the HDMI output. Change jumper JU2 to enable the
HDMI equalizer. The default setting is LEVEL = 1
with 200Ω back terminations.
Other Adjustments
1) To choose the lower power (LEVEL = 0) setting
without the 200Ω back termination resistors,
remove resistors R1, R2, R3, R4, and R5 for DVI
channel. Install a 0Ω resistor for R6. For the HDMI
channel, remove R7, R8, R9, R10, and R11. Install
a 0Ω resistor for R12.
2) To use a separate 3.3V supply, move the supply
select jumper (JU2) to the “EXT” position. Then
connect the 3.3V supply V CC to J4 (3.3V) and
ground to J5 (GND). See Figure 2.
Scope Measurements
The DVI and HDMI connectors make it difficult to make
electrical measurements with an oscilloscope that has
SMA connectors. To make such measurements with the
MAX3814 EV kit, adapter boards can be purchased
from Tektronix. The part numbers are DVI-TPA-R-DI for
the DVI socket and HDMI-TPA-P for the HDMI socket.
You can also contact Maxim’s Customer Applications
Group for the MAX3814 to get adapter board layouts.
