Overview

CompuLab Video Input Port Adapter (VIP-ADP) board is a peripheral board for connecting external video source devices to CompuLab COMs. VIP-ADP has a digital camera sensor connection port and two composite video input ports. Analog composite video is processed by TVP5151 NTSC/PAL/SECAM Video Decoder chip.

VIP-ADP board has several functional modes:

  • Digital video interface
  • Analog composite video input inteface
  • Serializer/deserializer interface

The selection between the modes is done by the on-board jumper (JP5).

VIP-ADP board setup

Following hardware is used as an example of VIP-ADP board connection:


The VIP-ADP board requires the following jumper settings to operate properly:

JP5 settings 1-2 4-6
Serializer/Deserializer *
TVP5151 Decoder
Camera sensor *


J1 settings OSC EXT
Select VIP-ADP as a clock source *
Select external clock source *


J2 settings INT EXT
Select internal power source *
Select external power source (P6) *


Digital camera sensor connection

The following VIP-ADP jumper settings are required to setup the digital camera:

  • Place a jumper on pins 4–6 of JP5.
  • Place a jumper on pins marked as "OSC" of J1.
  • Place a jumper on pins marked as "INT" of J2.

Camera sensor connection:

  • Connect the camera head-board to connector P7 of VIP-ADP. Make sure to match pins properly. MT9T031 sensor head-board connection example is illustrated in the picture above.
  • Connect VIP-ADP P3 to SB-T35 P26 Video Input port with a 40-wire flat cable.

Analog composite camera connection

The following VIP-ADP jumper settings are required to setup on-board TVP5151 decoder:

  • Remove JP5 jumper.
  • Remove J1 jumper.
  • Place a jumper on pins marked as "INT" of J2.

Camera connection:

  • Remove camera sensor head-board from connector P7.
  • Connect analog composite camera RCA connector to VIP-ADP composite input port P1.
  • Connect VIP-ADP P3 to SB-T35 P26 Video Input port with a 40-wire flat cable.

Known issues

SB-T35

  • SB-T35 P26 connector pin 6 (RESET#) is not connected. This pin can be used to reset the camera sensor (not required for Aptina MT9T031 sensor on VIP-ADP board).
  • SB-T35 P26 connector shifts 10bit of VIP-ADP camera data signals (PDATA[9:0]) two bits right, making the PDATA[1:0] signals not connected.
