Working Principles

The DS90UH948TNKDTQ1 is a high-speed serializer and deserializer designed for automotive applications. It converts parallel data from a source device into a serialized data stream for transmission over a high-speed LVDS interface. At the receiving end, it deserializes the data stream back into parallel data.

The chip incorporates equalization and pre-emphasis techniques to compensate for signal degradation caused by long-distance transmission and noise. This ensures reliable data transfer even in challenging automotive environments.

Detailed Application Field Plans

The DS90UH948TNKDTQ1 is widely used in various automotive applications, including:

1. Infotainment Systems: Enables high-quality video and audio transmission between head units and displays.
2. Automotive Cameras: Facilitates the transmission of high-resolution video signals from cameras to central processing units for advanced driver assistance systems (ADAS).
3. Display Systems: Allows the connection of high-resolution displays in automotive dashboards, rear-seat entertainment systems, and instrument clusters.
