MAX9503M

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 of MAX9503M from the EV kit are DCcoupled,eliminating large DC-blocking capacitors. The EV kit's input terminal has 75 termination to ground. The EV kit's output has a 75 back-termination resistor. The EV kit operates from a single 2.7V to 3.6V power supply.
