The Eclipse3 can supply a digital output using a THine
THC63DV164 DVI encoder. The Borealis Video Out Bus,
which supplies TTL level RGB and Sync, is sampled and
multiplexed and driven onto 4 differential pairs.
Because of the high frequency nature of the TMDS signals,
it is vital that matched length, shielded pair cable be used
for DVI connections.
The standard front panel analog VGA connector is replaced
by a DVI-I connector. This connector supplies both the
digital DVI (TMDS) signals and VGA. Rastergraf can
supply an adapter that allows a standard VGA cable to be
used when a DVI display is not desired or available.
A jumper can be installed to select Sync-On-Green
operation on boot-up. The signal has the following
approximate values:
1 Volt peak to peak consisting of:
The Borealis chip display timing is programmable. The
