Video Input Port Adapter Board
Contents
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 video is processed by TVP5151 NTSC/PAL/SECAM Video Decoder chip.
VIP-ADP board has several functional modes:
- Digital video interface
- 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:
- Compulab CM-T3730 module
- SB-T35 base board
- Aptina MT9T031 camera sensor installed on MT9T031C12STCH ES demo head board
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 3–4 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.
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.
