Overview
The DS90UB929TRGCR is a high-speed serializer designed for automotive and industrial applications, particularly in advanced driver assistance systems (ADAS) and infotainment systems. It supports the FPD-Link III interface, enabling the transmission of high-definition video data over a single coaxial or differential pair cable. This component is part of Texas Instruments' portfolio of serializer/deserializer (SerDes) solutions, known for their reliability and performance in harsh environments. The DS90UB929TRGCR integrates HDCP content protection, ensuring secure transmission of copyrighted content. It is designed to work seamlessly with compatible deserializers like the DS90UB928, forming a robust point-to-point communication link. The device is available in a compact WQFN package, making it suitable for space-constrained applications.
Structure and Working Principle
The DS90UB929TRGCR operates by converting parallel video data into a high-speed serial stream, which is then transmitted over a single cable to a compatible deserializer. The device supports data rates of up to 3.12 Gbps per lane, ensuring high-quality video transmission with minimal latency. It incorporates a bidirectional control channel, allowing for communication between the serializer and deserializer. The serializer includes built-in equalization and pre-emphasis features to compensate for signal degradation over long cables. It also supports DC-balanced encoding to minimize EMI and ensure reliable data transmission in noisy environments. The device is powered by a single 1.8V supply, with additional power-saving features to reduce overall system power consumption.
Key Features
The DS90UB929TRGCR offers several key features that make it ideal for demanding automotive and industrial applications. These include support for the FPD-Link III interface, which enables high-speed video transmission with embedded audio and control data. The device also includes HDCP 1.4 content protection, ensuring secure transmission of copyrighted material. Other notable features include robust EMI performance, thanks to DC-balanced encoding and spread spectrum clocking. The serializer supports long cable lengths (up to 15 meters for coaxial and 10 meters for shielded differential pair), making it suitable for large vehicle systems. Additionally, the device operates over a wide temperature range (-40°C to +105°C), ensuring reliability in extreme conditions.
Application Areas
The DS90UB929TRGCR is primarily used in automotive applications, such as ADAS, infotainment systems, and surround-view cameras. Its high-speed data transmission capabilities make it ideal for transmitting high-definition video from cameras to displays or processing units. The device is also used in industrial applications, such as machine vision systems and robotics. In automotive systems, the serializer is often paired with the DS90UB928 deserializer to create a robust video link. This combination is commonly found in rearview cameras, dashboard displays, and head-up displays. The device's ability to operate in harsh environments makes it suitable for use in heavy machinery and outdoor industrial equipment.
Maintenance and Precautions
Proper handling and maintenance of the DS90UB929TRGCR are essential to ensure long-term reliability. The device is sensitive to electrostatic discharge (ESD), so it should be handled with appropriate ESD precautions, such as using grounded wrist straps and anti-static work surfaces. Thermal management is also important, as excessive heat can degrade performance or cause failure. Signal integrity must be carefully considered during system design, particularly for high-speed data transmission. Proper impedance matching, cable selection, and PCB layout are critical to minimizing signal loss and EMI. The device should be stored in a dry, static-free environment when not in use, and exposure to moisture or corrosive substances should be avoided.
B2B Procurement Guide
When procuring the DS90UB929TRGCR, it is important to verify compatibility with existing system components, particularly the deserializer. Buyers should ensure that the device meets the required operating temperature range and signal integrity specifications for their application. It is also advisable to source components from authorized distributors to guarantee authenticity and quality. Pricing for the DS90UB929TRGCR can vary depending on order volume and supplier. Buyers should request samples or small quantities for testing before committing to large orders. Lead times may also vary, so it is important to plan procurement schedules accordingly. Technical support from the manufacturer or distributor can be invaluable for troubleshooting and system integration.
