The SN65DSI86-Q1 DSI to embedded DisplayPort (eDP) bridge features a dual-channel MIPI D-PHY receiver front-end configuration with four lanes per channel operating at 1.5 Gbps per lane and a maximum input bandwidth of 12 Gbps. The bridge decodes MIPI DSI 18-bpp RGB666 and 24-bpp RGB888 packets and converts the formatted video data stream to a DisplayPort with up to four lanes at either 1.62 Gbps, 2.16 Gbps, 2.43 Gbps, 2.7 Gbps, 3.24 Gbps, 4.32 Gbps, or 5.4 Gbps.
The SN65DSI86-Q1 is well suited for WQXGA at 60 frames per second, as well as 3D graphics at 4K and true HD (1920 × 1080) resolutions at an equivalent 120 fps with up to 24 bpp. Partial line buffering is implemented to accommodate the data stream mismatch between the DSI and DisplayPort interfaces.
