Typical Connection Diagram

A resistor may be necessary between the V

PAC VGA200 is in the power-down state. The value of this resistor should be chosen such that the extra charge deposited into

the V

repetition rate specified by the IEC-61000-4-2 standard is one pulse per second. When the PAC VGA200 is in the power-up

state, an internal discharge resistor is connected to ground via an FET switch for this purpose.

For the same reason, V

components in the system to provide a discharge path to ground.

GNDA, the reference voltage for the 75R resistors is not connected internally to GNDD and should ideally be connected to the

ground of the video DAC IC.
