The DS90UB913Q/914Q evaluation boards consist of two sections. The first part of the board provides the point-to-point interface for transmitting parallel video data. The second part of the board allows bi-directional control communication of an I2C bus control of using a MCU/FPGA to programming a remote peripheral device via the Serializer.

The DS90UB913Q/914Q chipset supports a variety of automotive mega-pixel camera systems over a two (2) wire serial stream. The single differential pair (FPD-Link III) is well-suited for direct connections between an imager and Host Controller/Electronic Control Unit (ECU)/FPGA. The bidirectional control channel of the DS90UB913Q/914Q provides seamless communication between the ECU/FPGA and the imager module. Transmission of a full-duplex high-speed video data (10/12 bits of parallel data, two SYNC bits and PCLK), with transparent bi-directional control channel (I2C) over the same serial video link. Additionally, there are four unidirectional general purpose (GPI and GPO) signal lines from the Deserializer to the Serializer. This interface allows transparent (no dependency of video blanking interval) ,full-duplex communication over a single high-speed differential pair. The Serializer and Deserializer communicate data at PCLK clocks speeds ranging from 10 to 100 MHz and I2C bus rates up to 400 kbps at up to 25 meters cable length over -40 to +105 Deg C.
