DS90UB921TRHSTQ1 Typical application Circuitry

DS90UB921TRHSTQ1

DS90UB921TRHSTQ1 is a high-speed serializer, primarily utilized for video data transmission in automotive environments. It is capable of converting parallel video and control data into a high-speed Serial Data Stream (SerDes). This chip is commonly found in applications such as automotive camera connections, Advanced Driver Assistance Systems (ADAS), and infotainment systems.

Application Scenario

A typical application scenario is the automotive rear-view camera system. In this scenario, the DS90UB921TRHSTQ1 can convert the image data captured by the camera into a high-speed serial data stream, which is then transmitted over a single twisted pair or coaxial cable to the vehicle's internal display or processing unit.

Parameter Features

- High-speed Data Transmission: Supports data transmission rates up to 1.5Gbps, ensuring real-time transmission of image data.

- Low Voltage Differential Signaling (LVDS) Interface: Provides a stable and reliable differential signal transmission method, reducing signal interference.

- Built-in Distortion Detection and Correction Mechanism: Enhances the reliability of data transmission, especially in harsh automotive environments.

Specific Circuit Connection

In designing a rear-view camera system, we will use the DS90UB921TRHSTQ1 as the core serializer part. Below are the specific wiring instructions:

- Camera Interface: Connect the parallel output interface of the camera to the parallel input pins of the DS90UB921TRHSTQ1. Ensure that the data lines, clock line, and synchronization signal lines are correctly connected.

- Power and Ground Wires: The DS90UB921TRHSTQ1 requires a stable power supply. Connect its power pin (VDD) to a stable 3.3V power source, and ensure all ground lines (GND) are connected to a common ground point.

- Serial Output: The high-speed serial output of the DS90UB921TRHSTQ1 will be connected to the display unit or processing unit using a corresponding receiver (such as DS90UB922). This is usually achieved through coaxial cables or twisted pairs.

- Configuration Pins: Some pins may need to be configured according to the specific application (such as output format, operating mode, etc.). Detailed configuration information should be referred to in the DS90UB921TRHSTQ1 technical manual.

Considerations in Design

- Electromagnetic Interference (EMI): Due to the significant electromagnetic interference in automotive environments, measures should be taken to reduce EMI, such as using shielded cables and optimizing layout.

- Power Disturbances: Automotive power supplies often come with high current surges during startup and shutdown, ensuring that the DS90UB921TRHSTQ1 can operate stably under these conditions.

- Temperature Adaptability: The temperature range in automotive environments is broad, and it is necessary to ensure that the DS90UB921TRHSTQ1 can operate normally within the specified temperature range.

- Reliability of Physical Connections: Due to the vibration and shock experienced by vehicles in motion, physical connections (especially high-speed serial connections) need to be highly reliable.

By considering the above factors comprehensively, a circuit designed using the DS90UB921TRHSTQ1 can provide efficient and reliable video data transmission functionality in automotive environments.
