4.2 Video Cards
4.2.1 VIB-X Video Board
Card P/N 903-0014-00 (Remote), 903-0015-00 (Console)
The VIB-X video interface board is a generic, 4-channel video card for use with Model 903 multiplexer
systems.
The VIB-X video interface board is configured with four SMB video jacks on the front panel, per Figure 4-5.
This 3U Eurocard is switch configured as either a video input card, used in the remote or subsea multiplexer
module, or a video output card, used in the console or surface multiplexer module. The current setting can be
verified by the front panel LEDs marked “Remote” or “Console” indicating whether the card is operating as a
video input (remote) or video output (console).
Figure 4-5: VIB-X Front Panel
The VIB-X cards are designed around an FPGA (Field Programmable Gate Array) connected to four input
circuits for digitizing video channels and four output circuits for regenerating analog signals from the digital
samples (see Figure 4-6). Switch settings on the VIB-X select the code loaded into the FPGA on power up,
which sets the front panel jacks as either video inputs or video outputs. Additional switches determine the
formats of the input/output signals. Video signals are digitized in 10-bit samples at 15.625 MHz with
FMB-X-2.5 cards.
