Specifications of MAX4450EVKIT

• Operating Supply Voltage: 5 V or 9 V

Required Equipment:
• Dual ±5.0V DC power supply
• Signal generation platform (e.g., Tektronix TG 2000)
• Video measurement set (e.g., Tektronix VM 700A)
The MAX4450 EV kit is a fully assembled and tested
surface-mount board. Follow the steps below for board
operation. Do not turn on the power supply until all
connections are completed.
1) Connect the output from the 75Ω video-signal
2) Connect the input of the 75Ω video measurement
3) For dual-supply operation connect the +5V supply
4) Connect the -5.0V supply to the VEE pad.
5) Set the signal generator for the pattern desired.
6) Turn on the ±5.0V DC power supply.
7) Analyze the filtered-output signal with the video
Note: The generator and the video test set must be
75Ω terminated. The signal source must provide a DC
return to ground. If it does not, place a 1kΩ resistor at
R11 to provide this. If the measuring device is high-
impedance, a 75Ω resistor must be installed at R7. If a
50Ω system is used, resistor R6 must be changed to
50Ω.
For single-supply (5V) operation connect V
The MAX4450 EV kit is a fully assembled and tested
surface-mount circuit board that demonstrates the
capability of the high-speed MAX4450 configured in a
3-pole, active lowpass, Sallen-Key filter circuit shown in
Figure 1. The filter can be used for video anti-aliasing or
as a reconstruction filter. The circuit is a Sallen-Key
realization with a gain of 2V/V for driving a 75Ω termina-

tion to an overall gain of 1. The board operates from a
±2.25V to ±5.5V dual-voltage supply or a +4.5V to
+11V single-voltage supply.
The MAX4450 circuit has been evaluated using the
Tektronix TG2000 generator and VM700 measurement
test setup as shown in Figure 2. The filter bandwidth
and differential gain and phase were measured using
the industry-standard Tektronix TG2000 and VM700 set
