Working Principles

The DS90UB948TNKDTQ1 is a video serializer and deserializer designed specifically for automotive applications. It converts parallel video data from image sensors into serialized data for transmission over long distances. On the receiving end, it converts the serialized data back into parallel format for further processing by the host processor.

The IC utilizes high-speed serial communication to transmit video data, enabling real-time video streaming. It also incorporates synchronization signals to ensure accurate data transmission between the image sensors and processors. The built-in error detection and correction mechanisms help maintain data integrity during transmission.

The DS90UB948TNKDTQ1 operates on a low power mode, reducing overall system energy consumption. It is designed to withstand the challenging conditions of automotive environments, providing reliable performance even in extreme temperatures and high vibration scenarios. Additionally, the IC includes EMI and ESD protection mechanisms to prevent signal interference and damage.
