7.4.3 LVDS Output Formats

The SN65DSI84 processes DSI packets and produces video data driven to the FlatLink™ LVDS interface in an industry standard format. Single-Link LVDS and Dual-Link LVDS are supported by the SN65DSI84; when the FlatLink™ output is implemented in a Dual-Link configuration, channel A carries the odd pixel data, and channel B carries the even pixel data. 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 SN65DSI84 transmits zero value pixel data on the LVDS outputs while maintaining transmission of the vertical sync and horizontal sync status.

Figure 9 illustrates a Single-Link LVDS 18bpp application.

Figure 10 illustrates a Dual-Link 24 bpp application using Format 2, controlled by CHA_24BPP_FORMAT1 (CSR 0x18.1) and CHB_24BPP_FORMAT1 (CSR 0x18.0). In data Format 2, the two MSB per color are transferred on the Y3P/N LVDS lane.

Figure 11 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 12 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 SN65DSI84 will not transmit the 2 LSB per color since the Y3P/N LVDS lane is disabled.

NOTE

Note: Figure 9, Figure 10, Figure 11, and Figure 12 only illustrate a few example applications for the SN65DSI84. Other applications are also supported.
