MAX9515 Evaluation Kit
General Description
The MAX9515 evaluation kit (EV kit) is a fully assembled
and tested surface-mount printed-circuit board (PCB)
that evaluates the MAX9515 video filter amplifier IC. The
MAX9515 features intelligent power management by
disabling the filter and output amplifier in the absence
of a video input signal and/or an output video load.
The MAX9515 features an internal reconstruction filter
with a ±1dB passband flatness at 9MHz and 50dB of
attenuation at 27MHz. The MAX9515 provides an inter-
nal fixed gain of 2V/V, accepts a full-scale video input
signal of 1V
P-P
(nominal) and provides an output full-
scale video signal of 2V
P-P
(nominal).
The MAX9515 EV kit video input and output are DC-
coupled. The EV kit video input has 75Ω termination to
ground and the output has 75Ω back termination. The EV
kit operates from a single 2.7V to 3.6V DC power supply.

MAX9515 Evaluation Kit
Evaluates: MAX9515
Quick Start
Required Equipment
Before beginning, the following equipment is needed:
• 2.7V to 3.6V, 500mA DC power supply (VDD)
• Video signal generator
•
Video measurement equipment (e.g., Tektronix VM-
700T)
Detailed Description of Hardware
The MAX9515 evaluation kit (EV kit) is a fully assembled
and tested surface-mount PCB that evaluates the
MAX9515 video filter amplifier IC. The MAX9515 fea-
tures intelligent power management by disabling the fil-
ter and output amplifier in the absence of a video input
signal at the EV kit’s input and/or an output video load
at the EV kit’s OUTPUT BNC connector. The EV kit
operates from a single 2.7V to 3.6V power supply that
provides up to 500mA.
The MAX9515 IC has an internal fixed 2V/V gain and an
internal reconstruction filter that smoothes the steps
and reduces the spikes on the video signal from the
video digital-to-analog converter (DAC). The recon-
struction filter has a ±1dB (typ) passband flatness to
9MHz and 50dB attenuation at 27MHz.
The MAX9515 EV kit accepts a full-scale video input
signal of 1V
P-P
(nominal) at INPUT and provides an out-
put full-scale video signal of 2V
P-P
(nominal) at the
MAX9515 IC output. The EV kit input is terminated to
ground by resistor R1 and the output is back terminat-
ed by resistor R2. The EV kit output expects to drive a
DC-coupled load to ground. Test points TP1 and TP2
are provided for observing the IC input and output sig-
nals, respectively. The MAX9515 internal level shift cir-
cuit positions the sync tip at approximately 300mV at
the TP2 output.
Procedures
The MAX9515 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) Connect the power-supply ground to the GND pad
on the EV kit.
2) Connect the power-supply positive terminal to the
VDD pad on the EV kit.
3) Connect the video signal generator output to the
INPUT BNC connector on the EV kit. The video
signal must be approximately 0 to 1V. If the video
signal is not between 0 and 1V, refer to the
How
to Level Shift Video Signals for DC-Coupled
Video Amplifiers/Filters
application note at
www.maxim-ic.com/appnotes.cfm/an_pk/4028.
4) Connect the OUTPUT BNC connector on the EV kit
to the input of the video measurement equipment.
5) Set the video signal generator for the desired video
input signal. This signal must contain sync information.
6) Turn on the power supply and set to 3.3V.
7) Turn on the video signal generator and enable its
output.
8) Analyze the video output signal with the video mea-
surement equipment.
Automatic Shutdown
When an input video signal is present at INPUT and a
load is connected at OUTPUT, the MAX9515 IC filter
and amplifier turn on and remain on until the output
load at OUTPUT is disconnected. The MAX9515 auto-
matic shutdown reduces the EV kit supply current to
< 9µA supply current based on the input signal pres-
ence and output loading.
Note:
If a video signal is not present at the EV kit
OUTPUT BNC connector, verify that a valid signal is
present at test point TP1 and a valid 75Ω load to ground
is connected at OUTPUT. The MAX9515 IC does not go
into full operation mode unless both of the above condi-
tions are satisfied. When connecting OUTPUT directly to
an oscilloscope, verify that the oscilloscope input is ter-
minated with a 75Ω load to ground.
