1. Product profile
1.1 General description
The IP4769CZ14 connects between the Video Graphics Adapter (VGA)/Digital Video
Interface (DVI) and the video transmitter like e.g. a PC graphic card or the VGA receiver
like e.g. a PC Monitor.
The IP4769CZ14 includes ElectroStatic Discharge (ESD) protection for the Data Display
Channel (DDC) signals, DDC level shifting and ESD protection for both
SYNChronization (SYNC) lines as well as high-level ESD protection diodes for the
Red-Green-Blue (RGB) signal lines.
The DDC level shifting can be used to shift the 5 V DDC bus at the connector side
to 3.3 V or 2.5 V on the internal side.

8. Application information
To maximize ESD clamping performance, the IP4769CZ14 should be placed as close as
possible to the VGA/DVI connector. The ESD protection channels VIDEO_1, VIDEO_2
and VIDEO_3 are identical and can be connected in any order with R, B, G signals to
simplify routing, and minimize stubs and vias. The SYNC protection lines are also
identical and can be used in any order for HSYNC or VSYNC signals. The DDC level
shifter lines are likewise identical in function.
The pull-up resistors on the DDC lines are dictated by the application, depending on the
values of the internal pull-ups provided in the Application-Specific Integrated
Circuit (ASIC), etc. Weak pull-ups may be required, for example, to pull up the DDC_INx
lines to VCC_5V when no monitor is connected, if the local ASIC does not include internal
pull-ups. Unexpected backdrive current can flow through these resistors though, when an
external monitor is powered and the local VCC_5V is powered down. Backdrive protection
should be considered if this is a concern.
