offers a complete product line of DVI and
DMI connectors. DVI (Digital Visual Interface)
was developed by the DDWG (Digital Display
Working Group) to improve analog and digital
image quality in PC applications. DDWGĄZs DVI
concept converts analog signals into digital
signals allowing PC-users to use of either
analog or digital monitors. The DVI interface
uses a single connector concept that interfaces
the legacy analog signals (VGA) and/or the
digital data protocol using TMDS (transition
minimized differential signaling) from the
PC to the display.
of bandwidth requirements and high-speed,
sharp-edged, clock rates, DVIĄZs single-cable
design is limited to a maximum length of 5-meters
(16.4-feet). DVIĄZs cable length limitation
presents few problems in PC-video applications
but can be problematic in home entertainment
applications because of the 5-meter length
limitation and the fact the DVI cabling and
connector interface does not have provisions
for audio. There are three standard DVI connection
Analog. DVI-A format interfaces the DVI signal
to an analog display (e.g., CRT monitor, HDTV,
et cetera) using a standard VGA (HD D-Sub
15) connector. The DVI design concept reserves
pins to interface the analog RGB and sync
signals from the PCĄZs graphics card to the
monitor or display.
Digital (Single & Dual Link). DVI-D format
interfaces direct digital signals from the
graphics card or video source to a digital
LCD or plasma display. PC graphics and images
are digitally developed and converted from
their native digital format to analog signals
by the PC graphics card before being transmitted
to the computer monitor using a VGA cable.
This VGA conversion process works well for
analog-based CRT monitors; but, when an LCD
display is used the VGA image must then be
converted back to its native format using
high-speed digital signal processing techniques.
DDWGs DVI-D interface concept eliminates the
need for double-conversion when LCD or plasma
digital displays are used.
Integrated Digital/Analog. DDWGĄZs DVI-I interface
concept supports either digital-to-digital
or analog-to-analog signaling. The DVI-I interface
does not support digital-to-analog or analog-to-digital
signaling. Today most LCD and plasma displays
are purely digital (DVI-D) while many support
the DVI-I interface meaning that the display
will accept either DVI-D or DVI-A signals.
