The IP4770CZ16, IP4771CZ16, IP4772CZ16 should be placed as close as possible to the
VGA/DVI interface connector.
The ESD protection channels VIDEO_1, VIDEO_2 and VIDEO_3 can be connected in
any order with RBG signals.
The 100 k resistors between the DDC_OUTx channels and VCC_5V are optional. They
may be used, if required, to pull-up the DDC_OUTx lines to VCC_5V when no monitor is
connected to the VGA connector. Backflow current can flow between pins DDC_OUTx
and VCC_5V via these resistors when VCC_5V is powered down.
