DS92LV18TVVX/NOPB Typical application Circuitry

DS92LV18TVVX NOPB

The DS92LV18TVVX/NOPB is a high-performance, low-voltage differential signaling (LVDS) 18-bit serializer/deserializer (SerDes) chip developed by Texas Instruments. This chip is specifically designed to facilitate high-speed, point-to-point data transmission over differential lines. The DS92LV18TVVX/NOPB efficiently converts 18 bits of parallel data into a serialized stream and vice versa, making it an ideal solution for applications requiring fast and reliable data transfer with minimal electromagnetic interference (EMI) and power consumption. It is particularly well-suited for use in high-speed communication systems, digital video interfaces, automotive camera systems, and any system requiring high-speed data transmission and cable minimization.

Key Features and Specifications:

- High-Speed Data Transmission: Capable of transmitting data at rates up to several Gbps, suitable for high-speed data communication.

- LVDS Interface: Uses Low-Voltage Differential Signaling for reduced power consumption and EMI.

- Integrated Clock Data Recovery (CDR): Ensures reliable data synchronization without the need for a separate clock signal.

- Compact Packaging: Offered in a compact package, facilitating integration into various systems.

Application Scenario: Automotive Camera System

In an automotive camera system, the DS92LV18TVVX/NOPB can be utilized to transmit high-resolution video data from a camera mounted on the vehicle to the main control unit. This setup is essential for features such as parking assistance, lane departure warnings, and rear-view video streaming.

Circuit Design Methodology:

1. DS92LV18TVVX/NOPB Camera Interface (Serializer Setup): Connect the parallel input pins of the DS92LV18TVVX/NOPB serializer to the camera's digital video output interface. These connections are crucial for capturing the parallel video data to be serialized.

2. Power Supply Configuration (VCC and GND Pins): Apply power to the VCC and ground (GND) pins of the DS92LV18TVVX/NOPB, using decoupling capacitors near these pins to ensure a clean, stable power supply for the serializer.

3. Serialized Data Transmission:

- Differential Output Connection (LVDSOUT+ and LVDSOUT-): Route the differential serialized data output from the DS92LV18TVVX/NOPB serializer to the deserializer located in the vehicle's main control unit. This connection is key to maintaining signal integrity and quality over the transmission distance.

4. Deserializer Integration (Control Unit Interface):

- Parallel Output Pins (To Control Unit): Connect the parallel output pins of the DS92LV18TVVX/NOPB deserializer to the main control unit's video processing interface. This setup is essential for converting the serialized data back into parallel format for processing and display.

5. Clock Recovery Mechanism:

- Integrated CDR Feature (No External Clock Necessary): Leverage the DS92LV18TVVX/NOPB's integrated clock data recovery mechanism to synchronize the data stream without requiring an external clock signal, simplifying the design and enhancing reliability.

Design Considerations:

- Signal Integrity: Ensuring the integrity of the LVDS signal is paramount, particularly over the extended distances typical in automotive applications. Proper shielding and differential pair routing are essential.

- Power Supply Stability: It is crucial to ensure that the power supply to the DS92LV18TVVX/NOPB is stable and clean to prevent data corruption.

- Thermal Management: Effective thermal management strategies should be employed to dissipate heat generated by the DS92LV18TVVX/NOPB, especially in the confined spaces of automotive environments.

- EMI Mitigation: Given the high-speed nature of the data transmission, implementing EMI mitigation techniques is critical to prevent interference with other electronic systems within the vehicle.

- System Latency: When designing the circuit, consider the latency introduced by serialization and deserialization processes, ensuring it aligns with the system's real-time processing requirements.

Implementing the DS92LV18TVVX/NOPB in an automotive camera system demonstrates its capability to handle high-speed video data transmission efficiently, leveraging its high-speed capabilities, integrated clock recovery, and LVDS interface to deliver superior performance. This application underscores the DS92LV18TVVX/NOPB's role in enabling advanced automotive safety and convenience features, highlighting its value in systems requiring robust and reliable high-speed data communication.
