1.5.2 DVI-I Connector
The DVI front panel connector is a DVI-I (analog/digital)
(http://www.ddwg.org/) connector. DVI uses the DVI TMDS encoded
data format, which allows longer data cables and reduces emitted noise.
Each of the three differential pairs carries nine digital video (TTL) lines. A
separate pair carries the PLL clock for the TMDS system. TMDS requires
that the length of all pairs must be closely matched. The Borealis boards
use a THine THC63DV164 DVI transmitter. Data sheets and application
notes are available on the THine web page (http://www.thine.co.jp).
You can access the VGA from the DVI-I connector with an adapter
(Molex 88741-8700, available from Digikey). It supplies analog video
(only) to a standard VGA connector. There is no split-off for DVI. You
can also get cables and/or adapters that provide both analog and digital or
just analog or digital.
Rastergraf strongly urges you to obtain commercially manufactured cables
and/or adapters that are available from Rastergraf, Molex, and other
suppliers. But, if you really want to roll you own, the board side connector
part number is Molex 74320-1004 with Molex 71781-0001 (or equivalent)
jackposts with Loctite. A cable that would work is Mogami W3206-8
(http://www.mars-cam.com/ccd/mogami/digital6.html).
