DVI Connector
|
The DVI [Digital Visual Interface] is a standard for high-speed,
high-resolution digital displays. Below is a 24 Pin DVI Female connector
seen at the Computer. The connector diagram and pin-out table show a
DVI-I Digital and Analog [RGB]; 29 pins [modified D style] connector. A
DVI-D Digital only connector with 24 pins [modified D style] looks about
the same with out the 4 analog 'C' pins. The DVI interface is found on a number of devices including TVs, Computers, Monitors, and Video cards. Digital Visual Interface was developed by the Digital Display Working Group (DDWG). Digital Video Broadcasting/Digital Audio-Visual Council (DVB/DAVIC), developed by DAVIC and DVB and adopted by European Telecommunication Standards Institute (ETSI) and International Telecommunication Union (ITU) |
DVI has a number of different types connectors:
DVI-D Digital only connector; 24 pins [modified D style];
DVI-A Analog only; [modified D style], I don't think this is part
of the standard
DVI-I Digital and Analog [RGB]; 29 pins [modified D style]
DFP Digital Flat Panel, Digital only connector. Pinout is listed

The pinout table above provides the pin out for a DVI-I connector,
supporting both digital and analog signals. Single Link DVI uses 12 of
the available pins providing a maximum bandwidth of 165MHz. Single Link
connectors do not use pins 4, 5, 12, 13, 20 and 21. Dual link DVI is
implemented when all 24 pins are used providing 2 x 165MHz bandwidth. The
analog signal are implemented by the 'micro-cross' pins; C1 - C5. The DDC interface pins use the I2C interface bus, as DDC Data for SDA, and DDC Clock as SCL. TMDS; Transition Minimized Differential Signaling The DVI-I connector may be used with a VGA connector by way of an adapter, while the DVI-D [Digital only] is not compatible. An Apple computer may have either a DVI connector as described above or a Apple display connector [ADC] which is an Apple proprietary interface connector. |
