1. general description 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 cc(sync) 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: ? ip4770cz16: r sync = 55 w ? IP4771CZ16: r sync =65 w ? ip4772cz16: r sync =10 w to allow termination of the sync lines all rgb i/os are protected by a special diode con?guration 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. 2. features n integrated high-level esd protection, buffering, sync signal impedance matching and level shifting n terminal connections with integrated rail-to-rail clamping diodes with downstream esd protection of 8 kv according to iec 61000-4-2, level 4 standard n back?ow protection on ddc lines n drivers for hsync and vsync lines n bidirectional level shifting n-channel fets available for ddc clock and ddc data channels n integrated impedance matching resistors on sync lines n line capacitance < 4 pf per channel n lead-free package and rohs compliant ip4770/71/72cz16 vga/video interface with integrated buffers, esd protection and integrated termination resistors rev. 01 25 october 2006 product data sheet
