3.10.6 PanelLink
The TP400 includes a PanelLink transmitter chip, which can be used to drive displays
located at up to 10 meters from the TP400.
PanelLink is a technology which converts the digital signals normally sent to a TFT
LCD into four high-speed serial data streams which can be transmitted over four
twisted pair cables. PanelLink was invented by Silicon Image, and has been adopted
by the DVI (Digital Visual Interface) consortium for use with digital monitors. For
further details of the technology see these web sites:
www.siimage.com
www.ddwg.org
To use the PanelLink interface on the TP400 the BIOS Setup program must be used
to enable and select a TFT display of the required resolution. Link LK19 must be set
to enable the PanelLink transmitter. If this is done then the transmitter will encode
and transmit the signals that are being generated for a local TFT display. Connection
can be made to the PanelLink signals at connector J7.
You will need to connect the TP400 to a PanelLink monitor through twisted pair cable.
In practice we have found that standard CAT5 Ethernet cable will work, but we would
recommend a higher quality, shielded cable, such as supplied by Molex as part of
their MicroCross DVI Connector System product range.
DSP Design may be introducing further PanelLink accessories. Ask us if you are
interested.
3.10.7 TV Clock
A signal called TV_CLK is available at the 40-way flat panel connector J8.
The TV_CLK signal is an optional input to the CS5530A chip. It can be used as the
timing reference for the graphics sub-system, therefore enabling the Geode graphics
sub-system to be synchronised to external TV signals.
DSP Design offers no software support for suing this signal.
