MAX11503 Evaluation Kit
Evluates:MAX1503
General Description
Features
♦ 2.7V to 5.25V Operating Range
♦ DC- or AC-Coupled Input
The MAX11503 evaluation kit (EV kit) is a fully assem-
bled and tested surface-mount printed-circuit board
(PCB). The MAX11503 EV kit evaluates the MAX11503
IC, a video amplifier with Y/C summer and chroma
mute. The MAX11503 operates at 3V (typ) and drives
two terminated 75Ω loads at an overall gain of +6dB.
♦ DC- or AC-Coupled Output
♦ Surface-Mount Construction
♦ Fully Assembled and Tested

MAX11503 Evaluation Kit
Jumper Selection
The EV kit incorporates jumper JU1 to control the
PSAVE pin. The PSAVE pin puts the device into a low-
power mode. See Table 1 for jumper JU1 settings.
Quick Start
Recommended Equipment
Before beginning, the following equipment is needed:
• 3V DC power supply
Table 1. Jumper JU1 Settings
• Video signal generator (e.g., Tektronix TG2000 or
similar)

Procedure
*Default position.
The MAX11503 EV kit is a fully assembled and tested
surface-mount PCB. 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 (power-up).
The EV kit incorporates jumper JU2 to control the
CMUTE pin. The CMUTE pin provides options to enable
or disable the chroma input signal from the summer.
See Table 2 for jumper JU2 settings.
2) Verify that a shunt is installed across pins 2-3 of
jumper JU2 (summer is enabled).

3) Connect the output of the video signal generator to
the Y_IN (luma) and C_IN (chroma) BNC connectors
on the EV kit.

5) Connect a 3V supply to the VCC pad. Connect the
supply ground to the GND pad.
Input Signals
The MAX11503 accepts either DC- or AC-coupled luma
input signals that are selected with jumpers JU3 and
JU4, as shown in Table 3. The MAX11503 is configured
for AC-coupled inputs by default. When using DC-cou-
pled inputs, make sure that the luma input signal has a
sync tip near ground.
6) Set the video signal generator for the desired video
input signals. This signal must contain sync informa-
tion (i.e., composite or Y).
7) Turn on the power supply and enable the video sig-
nal generator.
8) Analyze the output signal with the VM700A video
measurement equipment.

Detailed Description
The MAX11503 EV kit evaluates the MAX11503 3V
operation video amplifier with Y/C summer and a chro-
ma mute that can drive two terminated 75Ω video
loads. The MAX11503 EV kit accepts AC-coupled Y
(luma) and C (chroma) input signals summing them into
a composite CVBS output signal with gain of +6dB.

*Default position.
Output Signal
The MAX11503 EV kit can provide a sag-corrected DC-
or AC-coupled composite CVBS or Y (luma) signal. The
default output signal is set as DC-coupled composite
CVBS. To change the output signal to sag-corrected
AC-coupled, remove the R5 and R6 0Ω resistors and
install a 68µF and a 22µF aluminum electrolytic capaci-
tor on the C5 and C6 pads, respectively.
