General Description
Features
The MAX9654 evaluation kit (EV kit) is a fully assembled
and tested surface-mount PCB that contains the
MAX9654 triple-channel video-filter amplifier with selec-
table filtering for HD and SD video. The SD filter’s pass-
band is typically 8.5MHz and the HD filter’s passband
is typically 42MHz. The MAX9654 also has shutdown
control. The video inputs on the EV kit are AC-coupled;
the video outputs can be AC- or DC-coupled. In addi-
tion, the MAX9654 video inputs are terminated with 75Ω
and the video outputs have a 75Ω back termination
resistor. The EV kit operates from a single 3.3V DC
power supply.

MAX9654 Evaluation Kit
Quick Start
Recommended Equipment
Before beginning, the following equipment is needed:
Detailed Description of Hardware
The MAX9654 EV kit is a fully assembled and tested
surface-mount PCB that contains the MAX9654 triple-
channel video-filter amplifier with selectable filtering for
HD and SD video. The MAX9654 SD lowpass filter has
1dB passband out to 8.5MHz and 57dB attenuation at
27MHz. The MAX9654 HD lowpass filter has 1dB
passband out to 42MHz and 50dB attenuation at
109MHz. The MAX9654 EV kit has three input channels
to accept a full set of component video input signals.
•
•
3.3V DC power supply (VCC) capable of 50mA
Video signal generator (e.g., Tektronix TG-700 or
similar)
•
The appropriate video measurement equipment
(e.g., Tektronix VM5000)
Procedure
The MAX9654 EV kit uses 0.1µF ceramic capacitors to
AC-couple the video inputs to the MAX9654. The input
capacitor stores a DC level such that the outputs are
clamped to the appropriate DC voltage level. All video
inputs have a 75Ω termination to ground. The MAX9654
EV kit video outputs can be DC- or AC-coupled. By
default, 0Ω resistors are installed on R7, R8, R9, and
C4, C7, and C8 are open; each of the video outputs are
configured to drive DC-coupled video loads. To config-
ure the video outputs to drive the AC-coupled video
loads, remove R7, R8, and R9, and install the 220µF
capacitors on C4, C7, and C8.
The MAX9654 EV kit is fully assembled and tested.
Follow the steps below to verify board operation:
1) Verify that a shunt is placed on pins 1-2 of JU1 to
enable the MAX9654.
2) Verify that a shunt is placed on pins 2-3 of JU2 to
select HD video filtering.
3) Connect the outputs of the video signal generator to
the Y_INPUT, PB_INPUT, and PR_INPUT BNC con-
nectors on the MAX9654 EV kit.

4) Connect the Y_OUTPUT, PB_OUTPUT, and
PR_OUTPUT BNC connectors on the EV kit to the
input of the video measurement equipment.
Shutdown Mode
The MAX9654 EV kit provides an option to configure the
MAX9654 into shutdown mode. See Table 1 for shunt
positions.
5) Connect the power-supply ground to the GND pad
on the EV kit.
6) Connect the 3.3V supply to the VDD pad on the EV
kit.
