The MAX9503G evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board that evaluates
the MAX9503G, as well as the MAX9503M and
MAX9505 ICs. All of these ICs filter, amplify, and set the
black level to ground for standard-definition video signals.
These ICs feature an internal reconstruction filter
that has 3dB attenuation at 9MHz, 50dB attenuation at
27MHz, and ±1dB passband flatness to 5.5MHz.
Both the MAX9503G and MAX9505 provide a +6dB
gain, while the MAX9503M provides a +12dB gain.
The MAX9505 includes an analog switch that can be
configured as a video input, a video output, or a
microphone input.
Video input and output signals from the EV kit are DC-coupled,
eliminating large DC-blocking capacitors. The
EV kit's input terminal has 75Ω termination to ground. The
EV kit's output has a 75Ω back-termination resistor. The
EV kit operates from a single 2.7V to 3.6V power supply.
