SN65DSI83TPAPRQ1 Application Field and Working Principle

The SN65DSI83TPAPRQ1 is a DisplayPort-to-MIPI DSI bridge device from TexasInstruments. It is used to convert DisplayPort-signals from a system-on-chip (SoC) “client”to the MIPI DSI standard used by most LCDs.

Application Field

The SN65DSI83TPAPRQ1 is mainly used for mobile devices such as notebooks, tablets,and other embedded devices. It can be used in projects that require a cost-effectivemethod of converting DisplayPort signal to MIPI DSI signal, such as image sensors,medical applications, security and surveillance systems, automotive infotainment, anddigital signage applications.

Working Principle

The working principle of the SN65DSI83TPAPRQ1 is based on Single Stream Transport(SST) link training, where one link is established between the SN65DSI83TPAPRQ1 andthe SoC client device. The link is established in four phases, “idle”, “startup”,“configure”, and “operating”. The “idle” phase is used to initialize the link, the “startup”phase is used to detect the maximum link rate, and the “configure” phase is used toconfigure the link. The “operating” phase enables the actual data transmission.

Furthermore, the SN65DSI83TPAPRQ1 supports a wide range of resolutions, fromSVGA (800×600) to UHDTV (3840×2160). The resolution is determined by the SSTlink rate and video format negotiated between the DisplayPort-side and MIPI DSI-side source devices. The SN65DSI83TPAPRQ1 also supports up to eight data lanesfor the transmission of video and audio data.

Conclusion

In conclusion, the SN65DSI83TPAPRQ1 is a DisplayPort-to-MIPI DSI bridge devicethat is mainly used in the fields of mobile and embedded applications. The workingprinciple of the device is based on Single Stream Transport and link training, whereinthe device establishes a link between the two systems and supports resolutions up toUHDTV. The SN65DSI83TPAPRQ1 is an ideal solution for applications requiring acost-effective conversion from DisplayPort-signals to MIPI DSI.
