NXP Semiconductors IP4770CZ16

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. 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: Rsync = 55 Ω • IP4771CZ16: Rsync = 65 Ω • IP4772CZ16: Rsync = 10 Ω to allow termination of the SYNC lines 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.
