DS90UB964TRGCTQ1 Typical application Circuitry

DS90UB964TRGCTQ1

The DS90UB964TRGCTQ1 is a highly integrated automotive-grade deserializer chip from Texas Instruments, designed for advanced driver assistance systems (ADAS). It's part of the FPD-Link™ III series, optimized for receiving high-speed serialized data streams from automotive cameras and sensors, then deserializing this data for ADAS processing units. The chip supports high-definition video and data aggregation from multiple sources, making it an essential component in multi-camera automotive safety systems, such as surround-view systems, rear-view camera systems, and other sensor-based driver assist features.

Key Features and Specifications:

- Multiple Input Channels: Supports up to four FPD-Link III inputs, allowing connections from multiple cameras or sensors.

- High-Speed Data Transmission: Facilitates high-speed video and data transmission, crucial for real-time ADAS functionalities.

- I2C Master for Sensor Control: Integrates an I2C master to control connected sensors or cameras directly, simplifying system architecture.

- Automotive-Grade Reliability: Designed to meet the rigorous demands of automotive environments, including extended temperature ranges and vibration resistance.

- Coax or STP Cable Support: Enables transmission over coaxial or shielded twisted-pair (STP) cables, offering flexibility in vehicle wiring.

Application Scenario: Surround-View Camera System for a Vehicle

In this scenario, the DS90UB964TRGCTQ1 is utilized in a vehicle's surround-view system, aggregating video data from four cameras positioned around the vehicle to create a 360-degree view, aiding in parking and low-speed maneuvers.

Circuit Design Methodology:

1. Power Supply Connection (AVDD, DVDD, PVDD, GND): Connect AVDD, DVDD, and PVDD to a stable 3.3V power source, ensuring the device operates reliably. Connect all GND pins to the system's ground. It's critical to use decoupling capacitors near these power pins to filter noise.

2. Camera Input Connections (RX0+, RX0- to RX3+, RX3-): Interface the differential pairs from the output of the cameras to the RX0+ to RX3+ and RX0- to RX3- pins on the DS90UB964TRGCTQ1. Proper impedance matching and termination are vital for maintaining signal integrity.

3. I2C Bus for Camera Control (SDA, SCL): Connect the SDA and SCL pins to the cameras' control interfaces, allowing the DS90UB964TRGCTQ1 to configure camera settings and retrieve status information via I2C.

4. Deserializer Output to ADAS Processor (CSI-2 Interface): Utilize the MIPI CSI-2 interface pins to connect the deserialized video data output to the ADAS processing unit. This connection is essential for the high-speed transfer of video data for processing.

5. Configuration and Diagnostics (GPIO, INT): Employ the GPIO pins for system-level control signals and connect the INT pin to the processor to handle diagnostic alerts and status indications from the DS90UB964TRGCTQ1.

Design Considerations:

- EMI and Signal Integrity: Given the high-speed nature of data transmission, careful PCB layout to minimize EMI and preserve signal integrity is critical. Differential signal routing and shielding techniques should be employed.

- Power Supply Noise: The stability of the power supply is crucial for the DS90UB964TRGCTQ1's performance. Implement robust power management with automotive-grade components to handle the electrical disturbances typical in vehicles.

- Thermal Management: Ensure adequate thermal management strategies are in place, considering the DS90UB964TRGCTQ1's power dissipation and ambient temperature conditions in automotive environments.

- Camera and Cable Selection: The choice of cameras and the quality of coaxial or STP cables directly affect system performance. Ensure compatibility and reliability to maintain high video quality.

- System Redundancy and Safety: For safety-critical applications like ADAS, incorporating redundancy and fail-safe mechanisms is vital, especially in signal paths and power supply design.

Implementing the DS90UB964TRGCTQ1 in a surround-view system underscores its utility in handling complex video data aggregation and deserialization tasks, pivotal for enhancing vehicle safety and assisting drivers through accurate and comprehensive visual information. This setup demonstrates the DS90UB964TRGCTQ1's role in enabling sophisticated ADAS features by facilitating seamless integration of multiple video sources into a coherent and actionable data stream.
