The driver assist application highlights the challenge of having multiple cameras. This slide will discuss how the DS90UB901/02 addresses these challenges. First of all, this pair of products supports 14 bits of color as well as the sync signals. This is ideal for cameras which are typically 10 to 12 bits, while still providing room to expand to 14 bits of resolution for future needs. The 4-bit cyclic redundancy check, or CRC, provides error detection for both the video and control channels. It monitors the information being sent and flags the user if there is any data corruption going in both directions – the video data being sent from the camera to the processor or to any control information. In the driver assist application, these processors are often making very critical-safety decisions based on the data they are receiving, so it is important to have error detection. Programmable GPIOs are available, allowing the camera and host controller to talk to one another. Synchronization signals can be sent from the host to multiple cameras. These GPIOs can also switch at 58 kHz maximum frequency, which allows for a lot of flexibility with transmitting this data. An important feature for camera systems is the I²C slave address re-mapping. Some applications require multiple camera devices with the same fixed address to be accessed on the same I²C bus. The DS90UB901/02 provides slave ID matching to generate different target slave addresses when connecting more than two identical devices together on the same bus. This allows the slave devices to be independently addressed. Finally, the serializer provides a small footprint. It is in a 32-pin LLP package and is 5 mm x 5 mm, which fits very well inside small camera modules.
