SN65HVS880PWP Application Field and Working Principle

The SN65HVS880PWP is a high-speed serializer/deserializer (SerDes) device which is engineered with FPD-Link III technology from Texas Instruments. This device is designed to meet the performance requirements of automotive applications, such as advanced driver assistance systems (ADAS). The FPD-Link III technology allows for the transfer of high-speed video data over longer distances compared to other technologies. Furthermore, the SN65HVS880PWP enables the synchronous data transmission of up to 8-bit pixel data over either unshielded twisted pair (UTP) cables or shielded cables.

Application of the SN65HVS880PWP SerDes

The SN65HVS880PWP can be applied to a variety of applications, such as those related to image sensors, automotive driver monitoring systems, and on-board digital video recording. It is ideal for use in applications where a low-power digital link is desired. Additionally, it can be used for transmitting digital video information over standard cables at high speeds and for longer distances than other devices or solutions.

Working Principle of the SN65HVS880PWP

The primary purpose of the SN65HVS880PWP is to provide a digital link between an image sensor and the destination device. It can be used to transmit data at speeds of up to 10 Gbps and distances of up to 100 meters. It operates on a single 3.3V power source and can support up to 8-bits of pixel data. The device is also capable of power up to down conversion, allowing it to transmit data over a single pole cable.

In order to provide the high-speed transmission and longer reach, the SN65HVS880PWP implements FPD-Link III technology which consists of forward error correction (FEC), equalization, and clock and data recovery. FEC utilizes a low-free-phase shift keying (LFPSK) algorithm to correct errors that occur during transmission. Equalization modifies the signal to account for the variation of the communication channel. Clock and data recovery is the process of restoring the clock when encountering long segments of data.

Conclusion

In summary, the SN65HVS880PWP from Texas Instruments is a high-speed serializer/deserializer device for automotive applications. It implements the FPD-Link III technology to correct errors and equalize the signal, enabling the transfer of high-speed video data over distances of up to 100 meters with data rates of up to 10 Gbps. Additionally, the device can power up to down convert to send data over single pole cables.
