IP4773CZ14

General description

The IP4773CZ14 is a VGA or DVI-I interface intended to be connected between a video transmitter such as a PC graphics card and a VGA or DVI-I receiver, such as a PC monitor. The IP4773CZ14 has ESD protection for the DDC lines, ESD protection plus buffering for the h-sync and v-sync lines and high-level ESD protection diodes for the R, G, B video signal lines.

The synchronizing signals are buffered by non-inverting buffers which can accept TTL-level input. The buffers convert TTL-level input to CMOS-level output which swings between V_CC(SYNC) and GND.

An external termination resistor can be added to achieve the desired termination, which is typically required for the h-sync and v-sync lines of the video interface.

The IP4773CZ14 has a typical output resistance (R_O) of 10 Ohm.

Features

• Integrated high-level ESD protection, buffering, sync-signal impedance matching
• All pin connections have integrated rail-to-rail clamping diodes providing downstream ESD protection of +-8 kV according to IEC 61000-4-2, level 4
• Drivers for h-sync and v-sync lines
• Line capacitance < 4 pF per channel
