The SN65DSI83 device processes DSI packets and produces video data driven to the FlatLink LVDS interface in an industry standard format. Single-Link LVDS is supported by the SN65DSI83 device. During conditions such as the default condition, and some video synchronization periods, where no video stream data is passing from the DSI input to the LVDS output, the SN65DSI83 device transmits zero value pixel data on the LVDS outputs while maintaining transmission of the vertical sync and horizontal sync status.

Figure 7-4 illustrates a Single-Link LVDS 18 bpp application.

Figure 7-5 illustrates a Single-Link 24 bpp application using Format 2, controlled by CHA_24BPP_FORMAT1 (CSR 0x18.1). In data Format 2, the two MSB per color are transferred on the Y3P/N LVDS lane.

Figure 7-6 illustrates a 24 bpp Single-Link application using Format 1. In data Format 1, the two LSB per color are transferred on the Y3P/N LVDS lane.

Figure 7-7 illustrates a Single-Link LVDS application where 24 bpp data is received from DSI and converted to
18 bpp data for transmission to an 18 bpp panel. This application is configured by setting CHA_24BPP_FORMAT1 (CSR 0x18.1) to 1 and CHA_24BPP_MODE (CSR 0x18.3) to 0. In this configuration, the SN65DSI83 device does not transmit the 2 LSB per color since the Y3P and Y3N LVDS lane is disabled.
