IP4773CZ14

IP4773CZ14 VGA Interface with integrated buffer, ESD protection and termination resistor Rev. 01 — 24 February 2009 www.datasheet4u.com Product data sheet 1. 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 VCC(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 (RO) of 10 Ω. 2. Features I Integrated high-level ESD protection, buffering, sync-signal impedance matching I 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 I Drivers for h-sync and v-sync lines I Line capacitance < 4 pF per channel 3. Applications Buffer and terminating channels, reduce EMI and RFI, and provide downstream ESD protection for: I VGA interfaces including DDC channels I Desktop and notebook PCs, LCD TVs and PC monitors I Graphics c...
