The EV kit operates from a single +5V supply. The MAX7443 EV kit can also be used to evaluate the MAX7444, a similar device with a high-frequency boost option. Evaluates: MAX7443/MAX7444 MAX7443 Evaluation Kit 6) Connect the 5.0V supply to the terminal block labeled VCC. Connect the terminal labeled GND to the ground of the power supply. 7) Set the signal generator for the desired video signal, such as multiburst. 8) Turn on the 5.0VDC power supply. 9) Analyze any of the output signals with the VM700 video measurement. Detailed Description Jumper Selection The MAX7443 EV kit provides options for evaluation with a video signal generator output or a current output video DAC (encoder). Table 1 lists the jumper settings for selecting the input from either a video generator or a DAC (encoder). When interfacing to a video DAC or encoder output, the 200Ω termination resistor is provided on the board and selected by changing jumpers JU1 and JU3. A typical DAC termination resistor is 200Ω. If the full-scale DAC output current is different than ≈5mA, change the 200Ω resistor accordingly to get 1V at the input of the MAX7443. The MAX7443 EV kit incorporates jumper JU2 to control the gain setting. Table 2 lists the JU2 functions. Evaluating MAX7444 The MAX7443 EV kit can be also used to evaluate the MAX7444. To evaluate the MAX7444, replace the MAX7443ETA with a MAX7444ETA. Table 1.

The 162Ω resistor added to the standard 75Ω termination equals approximately 200Ω. Table 2.
