DS90UB913ATRTVJQ1

DS90UB913ATRTVJQ1 is an interface-level serializer and deserializer, providing a bridge between an external serial interface and an FPD-Link III differential data stream. It is ideal for automotive-grade applications such as automotive cameras, head units, and other high-speed video applications requiring up to four ports.This high-speed serializer/deserializer has the necessary features for use in automotive safety-related applications, such as active-target high-performance video, including the flexibility and scalability to support 1280x720p (60 fps) video and beyond. DS90UB913ATRTVJQ1 interface is FPD-Link III-compliant, with a programmable serializer for Ethernet and other serial applications.The main application field of DS90UB913ATRTVJQ1 is as an active-target (AT) serializer and deserializer for automotive video cameras, providing a bridge between the video signals from an automotive camera and the digital FPD-Link III. It is used to increase the speed of digital data serial signal transmission between the camera and the FPD-Link III interface. DS90UB913ATRTVJQ1 enables up to four camera channels to be connected to a single FPD-Link III interface, reducing the interconnect complexity of digital video applications.To understand its working principle, we must have some basic understanding of the way FPD-Link III digital serial signal transmission works. FPD-Link III uses three lines – FPDCLK+, FPDD+/-, and FPDCLK– – to transmit the differential signal from the source to the sink. The data transmission rate is up to 3 Gbps. DS90UB913ATRTVJQ1 provides the necessary power for the active sink, which is placed near the camera, and manages the heterogeneous rates of the serial interface and FPD-Link III interface. It has a programmable bandwidth that can be adjusted to match the speed of the camera as well as its transmission order. It also provides a delay lock loop (DLL) circuit to maintain differential signal integrity.The DS90UB913ATRTVJQ1 operates in two modes based on whether it is used as a serializer or deserializer. In serializer mode, it samples the input FPD-Link III data and encodes it into the serial format. In deserializer mode, it takes the incoming serial data and converts it into the differential FPD-Link III format. The device also includes an advanced power saving mode that reduces power consumption when the data transmission rate is low.In conclusion, DS90UB913ATRTVJQ1 is an interface-level device used in automotive video applications to bridge the gap between an external serial interface and an FPD-Link III differential data stream. The device offers high bandwidth, low latency, and the flexibility to support up to 1280x720p (60 fps) video and beyond. Its adjustable bandwidth and programmable serializer enable drive up to four camera channels to be connected to a single FPD-Link III interface, simplifying the connection of automotive video systems.
