To support legacy display transducer technology, analog signals may optionally be included in the same connector. Plug and play features are supported through the implementation of VESA EDID and VESA EDDC standards. Hot plug detection is provided to ensure industry compliance.1.2BackgroundT he DVI specification was created to ensure that a high-speed digital interface standard existed to transfer video data in a lossless digital domain and is licensed under the terms and conditions of the Digital Display Working Group, Digital Visual Interface Specification Revision 1.0 Adopter’s Agreement.1.3Reference DocumentsN ote: Versions identified here are current, but users of this standard are advised to ensure they have the latest versions of referenced standards and documents.•DDWG Digital Visual Interface, Revision 1.0, April 2, 1999•DDWG, Digital Visual Interface Specification Revision 1.0 Adopter’s Agreement.•ANSI/EIA Electrical Connector/Socket Test Procedures Including Environmental Classifications, Revision C, December 1994 (EIA-364-C)•VESA Enhanced Display Data Channel, Version 1, September 2, 1999 (EDDC)•VESA Enhanced Extended Display Identification Data Standard, Release A, September 2, 1999 (EEDID)1.4Part Number BreakdownThe DVI connector is available in a multiplicity of combinations, which will be detailed in this specification. Due to the difficulty in properly terminating the DVI plug, Foxconn does not sell plugs. For part numbers of DVI cable assemblies with plugs, please contact Foxconn sales. The Foxconn part number for ordering DVI receptacles is as follows:Figure 1-1 Receptacle Part Number Breakdown1.5Types of ConnectorsThe standardization effort leading to the DVI specification created two different interfaces, one that is digital only, known as DVI-D, and one that combines both analog and digital known as DVI-I.1.5.1 DVI Family of ConnectorsDVI compliant host systems may provide either a digital only interface or a combined analog and digital interface.The system-side (host) connector distinguishes the system capabilities. The two defined connectors have the same physical outer dimensions. In each case the digital signals are present, allowing a monitor with a digital interface to attach directly to either system connector. Because the digital only receptacle does not have sockets for the analog pins of an analog monitor, the plug of an analog monitor will not mate with the digital only system.The DVI-D plug connects to the digital only DVI-D receptacle and the DVI-I receptacle. The DVI-I plug only connects to the DVI-I receptacle. The relationship between the plug connectors and the corresponding host receptacles is shown below:Monitor: Plug Host: Receptacle DVI-I DVI-IAnalog video interfaceDVI-D DVI-DDigital video interface Digital Only HostThe DVI family of connectors uses physical features to ensure that displays using a given interface type (either analog or digital) will not be connected to hosts that cannot support them and will connect to interfaces.Analog interface monitors will use the DVI-I, which provides both analog and digital support.In order to accommodate the requirements of the ATX specification a variation of the PCB layout is also provided.The ATX layouts do not have the plastic locating posts and the grounding clip is a latching type that is designed to retain the connector into the board prior to soldering. For illustration of installation impact, compare the PCB patterns of DDWG versus the ATX, Section 2.7.1 versus 2.7.2 and 2.7.4 versus 2.7.5.1.5.2 DVI-I per DDWGThe combined digital and analog capable, right angle mounting receptacle with the PCB footprint as defined in the DDWG specification, is shown in Section 2.1; the associated PCB layout is shown in Section 2.7.4. Example of Foxconn part number is QH11121-CP0.1.5.3 DVI-I per ATXThe combined digital and analog capable, right angle mounting receptacle with the PCB footprint as modified in accordance with the design parameters of the ATX specification, is shown in Section 2.2; the associated PCB layout is shown in Section 2.7.5. Example of Foxconn part number is QH11121-CB0.1.5.4 DVI-I VerticalThe combined digital and analog capable, vertical mounting receptacle with a PCB footprint similar to that defined in the DDWG specification, is shown in Section 2.3; the associated PCB layout is shown in Section 2.7.6.

Example of Foxconn part number is QH11121-DP0.1.5.6DVI-D per ATXThe basic, digital only, right angle mounting receptacle with the PCB footprint as modified in accordance with the design parameters of the ATX specification, is shown in Section 2.5; the associated PCB layout is shown in Section 2.7.2. Example of Foxconn part number is QH11121-DB0.1.5.7DVI-D VerticalThe basic, digital only, vertical mounting receptacle with a PCB footprint similar to that defined in the DDWG specification, is shown in Section 2.6; the associated PCB layout is shown in Section 2.7.3. Example of Foxconn part number is QH11121-DW0.1.6Female ScrewlocksTo facilitate the many needs of Foxconn customers, DVI connectors are available without female screwlocks or with them installed in the connector. Determination of whether or not to have female screwlock supplied with the connector is specified by the last digit of the part number (see Figure 1-1). Female screwlocks may be ordered as a loose piece item, P/N 062-0004-049.

Connectors shall be designed to meet or exceed the performance and quality requirements enumerated in Section 4.3.4Signal AssignmentsDVI compliant host systems may provide either a digital only interface or a combined analog and digital interface. DVI is a defined interface connector. Variations of this signal assignment are not permitted.Note: Alteration of the pin assignments shown could result in the monitor and/or the host graphic board being damaged or destroyed. Due to the higher sensitivity of the digital receiver chipsets used in monitors, attention to connection details is very important.1 White color of insert in accordance with color requirements of Section 4 of PC ‘99/PC2001 Design Guide.3.4.1Digital Pin Assignments3.4.2Combined Digital and Analog Pin Assignments4.
