Description
PACVGA100/101 VGA Port ESD Protection and Termination Network
Features
Seven channel ESD protection
+15 kV ESD protection per channel, connector
Product Description
The PACVGA100/101 functions as a transmission line termination and ESD protection device for video applications. It provides 75 ohm parallel terminations for video R, G, and B lines and series terminations for the Horizontal Sync, Vertical Sync and the two DDC lines which serve as Plug and Play logic signals. In addition, all interface lines provide Level 4 ESD protection per the IEC 61000-4-2 contact discharge specification. The PACVGA100 provides internal pull-up resistors (R3) for the two DDC lines whereas the PACVGA101 omits these internal pull-ups so that different pull-up resistor values can be added externally.
