2.4.3 Front-End TTL Interfaces
LVDS Interface
The LVDS interface of the board variant CP331-LVDS is the standard interface for
remote digital flatpanel connections (up to 10m distance), with resolutions up to USXGA
quality (1280 x 1024). Due to its universal use, it is routed directly on-board. The
installed transmitter chips are the National Semiconductor DS90C5(3)83 or Texas
Instruments SN75LVDS83.
Figure 2-3: Orientation of LVDS Connector
The front-end connector is a 26-pin Mini-Delta Ribbon (MDR) con-
nector which provides all required signals including the 5V and
12V supplies and several control signals used by external key-
boards, touch screens or similar peripheral devices.
Embedded within the LVDS cable are the +5V DC, +12V DC and
control lines required for remote display connection together with
additional (general purpose) lines provided for touch panel dis-
plays, keyboards, mouse, etc.
The pinouts of the LVDS connector is compliant with Apllication
Note AN-1085 FPD-Link by National Semiconductors as shown in
the below table.
Note...
Dual-scan flat-panels cannot use this interface due to inconsis-
tent clock requirements.
