The DS90UH949TRGCTQ1 is a serializer/deserializer, also known as a serdes, which provides a single high speed serial link interface to one or two high resolution video ports (YUV/RGB, 8/10/12 bit). This industrial-grade chip is well suited for cost-sensitive camera and display applications.

The device’s superior performance makes it suitable for a variety of applications, including automotive, industrial, medical, interference-prone environments, and consumer applications. It supports up to 4.25 Gbps HSYNC or 3.75 Gbps PrP input/output data rates, with higher data rates possible using a Clock and Data Recovery (CDR) device.

The device can be used as a serializer or deserializer, depending on the application. When used as a serializer, it can convert one or two parallel video inputs into a high speed serial output, allowing for more efficient use of high-speed data busses. When used as a deserializer, it can convert an incoming serial data stream into multiple parallel video outputs. In both configurations, it supports all standard video formats, and can handle both interlaced and progressive input signals.

The DS90UH949TRGCTQ1 is an all-digital device, meaning there is no analog circuitry. It operates on a single 1.8V supply with an I/O voltage level range of 1.2V to 2.5V. The device is flexible and configurable, with a wide range of output and input colorspaces andpixel cycles to choose from. It consists of a Input Controller, Input Mux, Serializer, Data Recovery Clock, Deserializer, and Output Controller.

The Input Controller acts as a bridge between the input ports and the rest of the device. It operates in one of three different modes, which can be selected depending on the application. Direct mode bypasses color space conversion and all the video data is sent directly to the serial output. In RGB mode, each of the three RGB color components are serialized separately and sent in order, while in YUV mode the data is first converted to YUV color space before being sent.

The Input Mux selects the active port and synchronizes the stream before sending it to the Serializer. The serializer converts the parallel data into a single serial stream and has an on-chip PLL for clock and data recovery. The deserializer is responsible for converting the serial stream back into the original parallel format. Finally, the output controller converts the data to the desired color format and sends it to the output port.

The DS90UH949TRGCTQ1 is an ideal device for a variety of applications requiring high-speed, reliable data transfer. It is designed for flexibility, allowing designers to customize and optimize their designs for a broad range of video applications. The device’s features and performance make it an ideal solution for applications in the industrial, automotive, medical, and broadcast video markets.
