DS90UB921TRHSRQ1 Serializer And Deserializer Application and Working Principle

Serializers and deserializers (serdes) are hardware devices used to convert digital data streams into transmission format for high speed communication. They are essential for meeting the increased demand for higher data rates. The DS90UB921TRHSRQ1 is a fully-featured, low-power mixed-signal serializer/deserializer device designed to transmit and receive high-speed video data. This article explores the application fields and working principles of the DS90UB921TRHSRQ1 serdes.

DS90UB921TRHSRQ1 Application Fields

The DS90UB921TRHSRQ1 can be used in a variety of applications such as audio-video (AV), computational imaging and machine vision, automotive infotainment, automotive controls, industrial, medical and other industrial applications.The device is especially suitable for use in automotive applications such as rear-view camera systems, automotive infotainment systems, and vehicle-to-vehicle communication. It can also be used in industrial controller systems, medical imaging applications and other industrial applications where high-speed data transfer is required.

DS90UB921TRHSRQ1 Working Principle

The DS90UB921TRHSRQ1 device is a fully integrated serializer/deserializer that supports up to four lanes of data transmission at a maximum data rate of up to 2.5 Gbps. It is designed to transmit and receive video data streams in a manner that is optimized for video transmission over copper cable, fiber optics, or other mediums.The device is designed to operate on an LVDS or Low Voltage Differential Signaling protocol, which is widely used in the automotive industry. LVDS features low power consumption and low electromagnetic interference (EMI). The device is also designed to support multiple data rates up to 2.5 Gbps. The device contains several key components such as a transmitter, receiver, LVDS packetizer, PLL, and a controller. The transmitter can take high-speed differential signals from a data source, such as a video processor, and convert them into LVDS packets for transmission. The LVDS packetizer reconfigures the serialized data stream into the LVDS format for transmission. The PLL synchronizes the LVDS signals to ensure that data can be reliably transmitted and received across the link.The device also features a controller (equalizer) that is designed to minimize ISI, or Inter Symbol Interference, which can lead to data errors if left unchecked. The equalizer works by looking at the incoming data and then applying equalization to reduce the amount of signal distortion caused by ISI. This helps ensure that data can be accurately transmitted without errors.

Conclusion

The DS90UB921TRHSRQ1 serializer and deserializer is a versatile device designed for use in a variety of applications, including automotive infotainment, automotive controls, industrial and medical applications. It is capable of transmitting and receiving high-speed video data streams using the LVDS protocol at speeds up to 2.5 Gbps and supports a variety of data rates. The device includes components such as a transmitter, receiver, LVDS packetizer, PLL, and equalizer to ensure reliable data transmission.
