The DS90UH947TRGCRQ1 is an integrated serializer and deserializer that supports numerous popular interface protocols. Its ability to encode and decode between native differential high-speed data transfers and low-speed differential serialized data transitions makes it an invaluable tool for applications involving high-speed communication in demanding environments.

Application Field

The DS90UH947TRGCRQ1 is a high-speed serializer/deserializer (SerDes) designed specifically for bidirectional data communication in high-speed industrial, automotive and consumer applications. The device supports flexible interface protocols, including Serial Peripheral Interface (SPI), Inter-Integrated Circuit (I2C), and Mipi Camera Serial Interface 2 (CSI-2). It combines both serializer and deserializer functions into a single package, making it suitable for bidirectional data transmission. The device also has an integrated FIFO memory that makes it capable of sending and receiving data simultaneously.

The integrated SerDes can be used in many applications, such as industrial automation, automotive infotainment, medical imaging, drones and robotics, and the internet of things (IoT). The device helps for improvement in bandwidth, power consumption and reliability of systems which need bidirectional high-speed data communication. The device is capable of transferring data between two systems at up to 1 GB/s speed in each direction.

Working Principle

The device basically integrates both serializer and deserializer functionality into a single package. It contains a differential transmitter and an equalizer-receiver that convert 8-bit or 16-bit parallel data into serial data. The serializer performs differential encoding of data, while the deserializer performs equalizing and BER (Bit Error Rate) correction. The data can be transmitted over distances as long as 20 meters.

The SerDes supports data rates ranging from 55 Mbps to 1 Gbps with superior signal integrity. It has an integrated FIFO that operates in low-power EMI (Electromagnetic Interference) mode, ensuring that data is transmitted and received in the most reliable way. The device also supports scrambler and checksum functions for added data reliability.

The device is also equipped with clock recovery circuit to detect and supply clocks for data transfer. Furthermore, the device has a wide range of power supply voltages, ranging from 1.1 V to 1.5 V. It also features half-rate or full-rateTx/Rx data modes. The device can also be configured to adjust the speed of data transmission or the time taken to transfer a single data block.

The device supports a number of industry standard interface protocols and is also compliant with CAN (Controller Area Network) and UART (Universal Asynchronous Receiver/Transmitter) interface. It supports data transfer over short and long distances and can operate in both differential and single-ended line configurations. The device also includes boundary-scan and self-test capabilities for improved reliability.

In short, the DS90UH947TRGCRQ1 is a highly integrated serializer and deserializer that supports multiple interface protocols. It offers extremely high-speed bidirectional data communication and an integrated FIFO memory for simultaneous data transmission and reception. The device can transfer data over long distances with excellent signal integrity thanks to its equalizers and power-efficient EMI mode operation. It also features industry-standard protocols, boundary-scan and self-test capabilities, and adjustable speed and time-to-transfer options.
