The DS90UB949TRGCRQ1 is a serializer device with the following functions:
1. Serialization of Data
High – Speed Data Serialization: It is designed to convert parallel data into a serial data stream. This is crucial for efficient data transmission over long distances or in applications where the number of wires needs to be minimized. For example, in automotive camera systems, it can take the parallel data from an image sensor and serialize it to send the data through a single cable to the processing unit.
Data Formatting: The device formats the data during serialization to meet specific transmission requirements. It adds necessary headers, trailers, or error – correction codes to the serial data stream as per the communication protocol. This ensures the integrity and proper interpretation of the data at the receiving end.
2. Video and Image Signal Processing
Video Signal Handling: In video – related applications, it processes video signals. It can handle different video formats and resolutions. For instance, it is capable of working with high – definition (HD) and ultra – high – definition (UHD) video signals from cameras or other video sources. It compresses or encodes the video data to a suitable format for serialization and transmission.
Image Signal Support: Besides video, it also supports the serialization of image signals. It can manage the data from image – capturing devices such as cameras used in surveillance systems or automotive advanced driver – assistance systems (ADAS). It ensures that the color, contrast, and other image – related information are properly serialized and transmitted.
3. Interface and Connectivity
Multiple Input Interfaces: The DS90UB949TRGCRQ1 has various input interfaces to receive data from different sources. It can interface with parallel data buses, video connectors, or other types of input ports. This flexibility allows it to integrate with a wide range of sensors and data – generating devices.
Output Serial Interface: It provides a high – speed serial output interface. This interface is designed to connect to a deserializer at the receiving end. The serial output uses a specific transmission protocol and data rate to send the serialized data over a cable or other transmission medium. The output interface is often designed to reduce electromagnetic interference (EMI) and crosstalk during data transmission.
4. Data Transmission and Link Management
Long – Distance Transmission: The device enables long – distance data transmission of video and other signals. It uses techniques such as equalization and data encoding to overcome signal degradation over long cable lengths. This makes it suitable for applications where the data – generating device and the receiving unit are located far apart, like in industrial automation or large – scale surveillance systems.
Link Monitoring and Error Detection: It monitors the data link during transmission. It can detect errors such as bit – errors, packet – losses, or transmission – interruptions. When an error is detected, it may trigger an error – reporting mechanism or attempt to correct the error using built – in error – correction capabilities. This ensures the reliability of the data transmission link.
5. Power Management and Configuration
Power Supply and Consumption: The DS90UB949TRGCRQ1 operates under a specific power – supply voltage range. It manages its power consumption based on the operational state. For example, it may have different power – consumption levels during data transmission, standby, or configuration modes. This allows for efficient power usage in different application scenarios.
Configuration Registers: It has configuration registers that can be used to set up various parameters. These parameters include data – rate settings, video – format selection, and input – output – interface configurations. The ability to configure the device through registers provides flexibility to adapt to different application requirements and data – source characteristics.
