1. General description
2. Features
The IP4770CZ16, IP4771CZ16, IP4772CZ16 is connected between the VGA/DVI
interface and the video graphics controller and includes level shifting for the DDC signals,
buffering for the SYNC lines as well as high-level ESD protection diodes for the RGB
signal lines.
The level shifting functions are required when the DDC controller operates at a lower
supply voltage than the monitor. To use this level shifting function the gates of the two
N-channel MOSFETs have to be connected to the supply rail of the DDC transceivers.
Buffering for the SYNC signals is provided by two non-inverting buffers, which accept TTL
input levels and convert these to CMOS compliant output levels between pins V
and GND.
The IP4770CZ16 and IP4771CZ16 contain the formerly external termination resistors,
which are typically required for the HSYNC and VSYNC lines of the video interface:
All RGB I/Os are protected by a special diode configuration offering a low line capacitance
of 4 pF (maximum) only to provide protection to downstream components for ESD
voltages as high as 8 kV contact discharge according to IEC 61000-4-2, level 4 standard.
