Description 1. DESCRIPTION The SERUB-16OVT only the Serializer board based on the SERDESUB-16OVT kit. The SERUB-16OVT is an evaluation kit designed to demonstrate performance and capabilities of the DS90UB901Q and DS90UB902Q FPD-Link III Serializer/Deserializer Chipset for use with the OmniVision sensors. This serves as an add-on to the OmniVision development systems by providing a serialized digital interface between camera and controller.

Setup Instructions 4. SETUP INSTRUCTIONS 1. Connect the DS90UB901Q Serializer board to the Omnivision module via the J1 32-pin header (16 x 2 x 0.1"). Ensure that the camera module and the Serializer board are connected properly by matching the ground (GND) pins. 2. Connect the DS90UB902Q Deserializer board to the Host Controller. 3. Connect the DS90UB901Q Serializer board to the DS90UB902Q Deserializer board via CAT6 cable on the RJ45 connectors. 4.

Operation 6. OPERATION This section describes how to I2C instructions between Host and image sensor through the DS90UB902Q and DS90UB901Q pair function in a camera system application. Figure 4 shows the configuration of evaluation boards for I2C communication with a Host controller. Note a Host controller requires an I2C interface with slave clock stretching support. In Camera mode, I2C transactions originate from the Master controller at the Deserializer side (Figure 4).
Operation TROUBLESHOOTING CHART Problem… No image Solution… Check that RJ45 green lights are on No green light on RJ45 connectors Check that 5V power supply is applied, and CAT cable connection is good All lights on, but no image Cycle “ON” button on Deserializer board Check that orientation of board connections is correct No image Check that lens cap is removed from camera Power, ground, input data and input clock are connected correctly, but no outputs.
