General Description
The MAX9516 evaluation kit (EV kit) is a fully assembled
and tested surface-mount printed-circuit board (PCB)
that evaluates the MAX9516 video IC. The MAX9516
amplifies standard-definition video signals and sets the
output video black level near ground, while consuming
minimal power. The MAX9516 has an internal recon-
struction filter, provides an internal fixed gain of 8V/V,
accepts a full-scale video input signal of 0.25VP-P
(nominal), and provides an output full-scale video sig-
nal of 2VP-P (nominal).
The MAX9516 EV kit video input signal is configured for
both DC- and AC-coupled operation. The EV kit video
input is terminated with a 75Ωresistor to ground and
the output is back terminated with a series 75Ωresistor.
The EV kit also includes an output LOAD signal, which
indicates when a valid output load is present. The EV kit
operates from a single 1.7V to 2.625V DC power supply.

Quick Start
Recommended Equipment
• 1.7V to 2.625V, 500mA DC power supply (VDD)
• Video signal generator
• Video measurement equipment (e.g., Tektronix VM-
700T)
• Oscilloscope
Procedure
The MAX9516 EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed.
1) Verify that a shunt is installed across pins 1-2 of
jumper JU1 (EV kit enabled).
2) Connect the power supply ground to the GND pad
on the EV kit.
3) Connect the power supply positive terminal to the
VDD pad on the EV kit.
4) Connect the output of the video signal generator to
the IN BNC connector on the EV kit. The video signal
must be biased such that the sync tip is at ground.
5) Connect the OUT BNC connector on the EV kit to
the input of the video measurement equipment.
6) Connect the scope probe to the LOAD pad and the
ground lead of the scope probe to the GND pad.
7) Set the video signal generator for the desired video
input signal. This signal must contain sync information.
8) Turn on the power supply and set it to 1.8V.
9) Enable the video signal generator.
10) Verify that the voltage level at LOAD is equal to 1.8V.
11) Analyze the video output signal with the video mea-
surement equipment.
Detailed Description
The MAX9516 evaluation kit is a fully assembled and
tested surface-mount PCB that evaluates the MAX9516
video IC. The MAX9516 amplifies and sets the output
video black level near ground for standard-definition
video signals, while consuming minimal power. The EV
kit operates from a single 1.7V to 2.625V power supply
that can supply up to 20mA.
The MAX9516 IC has an additional internal reconstruc-
tion filter that smooths the steps and reduces the
spikes on the video signal from the video digital-to-ana-
log converter (DAC). The reconstruction filter typically
has 3dB attenuation at 10MHz, 46dB attenuation at
27MHz, and ±1dB passband flatness to 8.1MHz.
The MAX9516 provides an internal fixed 8V/V gain. The
EV kit accepts a full-scale video input signal of 0.25VP-P
(nominal), and provides an output full-scale video signal
of 2VP-P (nominal).
The MAX9516 EV kit video input signal is by default con-
figured for DC-coupled operation. The MAX9516 has a
transparent input sync-tip clamp, allowing AC-coupling
of input signals with different DC biases. The MAX9516
video input on the EV kit can also be configured for AC-
coupling operation by removing resistor R1. The EV kit
input is terminated to ground by resistor R2 and the out-
put is back terminated by resistor R3. The MAX9516 EV
kit also features a LOAD signal output pad, which indi-
cates when a valid output load is present. An additional
VLOGIC pad and pullup resistor R4 is included for a
future product.
Jumper Selection and
Other Configurations
Shutdown Mode (
SSHHDDNN
)
Jumper JU1 controls the MAX9516 shutdown mode
(SHDN). The shutdown mode turns off the sync-tip
clamp, filter, amplifier, charge pump, and internal linear
regulator, thus reducing the IC’s quiescent supply cur-
rent to 10nA (typ). See Table 1 for jumper JU1 selection.
Load Detect Indicator
The MAX9516 EV kit provides a LOAD output pad that
indicates when a valid video load is present at OUT.
The LOAD signal is a logic-high when a valid video
load is present at OUT, and a logic-low when a valid
video load is not present at OUT.
AC-Coupled Input
The default setting of the MAX9516 EV kit is set for a
DC-coupled input. However, the kit can be configured
for an AC-coupled input by removing resistor R1.
