Product Description
The PACVGA100/101 functions as a transmission line
termination and ESD protection device for video appli-
cations. 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.

Note 1: For best ESD protection, minimize R/G/B trace lengths
between the PACVGA100/101 device and the video
connector.
