PAC VGA-100/101
SCHEMATIC CONFIGURATION
Features
Product Description
The PAC VGA-100/101 acts as a transmission line terminating and ESD protection device. It provides 75 Ohm parallel
terminations for the R, G, B lines and series terminations for the Horizontal and Vertical Sync lines and two monitor ID
lines which provide Plug and Play logic signals. In addition, all interface lines provide Level 4 ESD protection per the
IEC1000-4-2 contact discharge Specification. The PAC VGA-100 provides internal pull-up resistors for the two monitor ID
lines. The PAC VGA-101 omits these internal pull-ups so that different pull-up resistor values can be added externally.
