The MAX4090 evaluation kit (EV kit) provides a proven design to evaluate the MAX4090 3V/5V, 6dB video buffer with sync-tip clamp. The MAX4090 video input terminals have a 75Ω termination resistor to ground, and the output terminals have a 75Ω back-termination resistor. The EV kit operates from a single 2.7V to 5V DC power supply.
The MAX4090 EV kit uses the sag correction configuration. The video input and output signals on the EV kit are AC-coupled.
The MAX4090 can also be used to drive DC-coupled, 150Ω back-terminated video loads in portable video applications. See the Output Signal section in the full data sheet to use the MAX4090 as a DC-coupled output driver.
The MAX4090 EV kit PCB comes with the MAX4090AAUT+ installed. The MAX4090 EV kit can also be used to evaluate the MAX4090EUT+. Contact the factory for free samples of the pin-compatible MAX4090EUT+ device.
