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

Note: To emulate a 200 Ω DAC source resistor when driving from a 75 Ω generator, remove jumpers JU4 and JU5. The 162 Ω resistor
added to the standard 75 Ω termination equals approximately 200 Ω .

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 provid-
ed 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.
The MAX7443 EV kit can be also used to evaluate the
MAX7444. To evaluate the MAX7444, replace the
MAX7443ESA+ with a MAX7444ESA+.
