Working Principles

The DS90UH949ATRGCTQ1 is a high-speed serializer and deserializer (SerDes) designed for automotive applications. It enables the transmission of high-resolution video and audio signals between electronic components in vehicles.

The device receives parallel data from the source and converts it into a high-speed serial stream using serialization. This serialized data is then transmitted over a long-distance communication link, such as a coaxial cable or twisted pair, to the receiving end.

At the receiving end, the DS90UH949ATRGCTQ1 deserializes the received serial data back into parallel form, which can be easily processed by the receiving electronic component. The device also performs signal conditioning, equalization, and pre-emphasis to ensure high signal integrity and minimize data errors.

Detailed Application Field Plans

The DS90UH949ATRGCTQ1 is primarily used in automotive applications where high-speed video and audio transmission is required. Some of the specific application fields include:

1. Infotainment Systems: Enables the transmission of high-resolution video and audio signals from media sources to display units in the vehicle's infotainment system.
2. Rearview Cameras: Facilitates the transmission of video signals from rearview cameras to the vehicle's dashboard display, providing drivers with enhanced visibility while reversing.
3. Advanced Driver Assistance Systems (ADAS): Supports the transmission of video signals from ADAS sensors, such as cameras and LiDAR systems, to the central processing unit for real-time analysis and decision-making.
4. In-Vehicle Networking: Enables high-speed communication between various electronic components within the vehicle, such as displays, control units, and sensors.
