The MAX7438 evaluation kit (EV kit) is a fully assembled
and tested surface mount board. The MAX7438 EV kit
includes the MAX7438, a three-channel standard-defin-
ition video reconstruction filter with a back-porch clamp
that sets the output blanking level of the video signal to
ground. The MAX7438 has an internal gain of +2V/V,
and the EV kit provides five levels of high-frequency
boost. The EV kit operates from ±5V dual supplies.
The MAX7438 EV kit can also be used to evaluate the
MAX7439, which is a three-channel, standard-definition
video reconstruction filter with an internal gain of +3V/V.

The MAX7438 EV kit is a fully assembled and tested
surface-mount board. Follow the steps below to verify
board operation. Do not turn on the power supply
until all connections are completed:
1) Verify that there are shunts across jumpers JU6,
2) Verify that a shunt is installed across pins 1 and 2
3) Verify that the rest of the jumpers are open.
4) Connect the output of the video signal generator to
5) Connect the OUT1 BNC connector on the EV kit to
