TC358860XBG(ES)

TC358860XBG converts an Embedded Display Port (eDPTM) video stream into an MIPI® DSI stream. There are four eDP main link lanes in TC358860XBG, they can toggle at either 1.62, 2.16, 2.7, 3.24, 4.32, or 5.4 Gbps/link to receive up to 17.28 Gbps (5.4 Gbps x 0.8 x 4) of video stream. The 4-data lanes dual link DSI Tx can transmit up to 8 Gbps (1 Gbps x 4 x 2) of video stream. For input video stream with bandwidth (BW) < 4 Gbps, TC358860XBG can output the video data either with a single DSI link or performs left-right line split to output the video data stream with dual DSI links. For input video stream with BW requirements between 4 Gbps and 8 Gbps, left-right line split and dual DSI links usage is necessary.

TC358860XBG provides a compression engine which compress video data with 2-to-1 ratio. This enables TC358860XBG to receive 4K @60fps video streams at eDP Rx, compress and send out to a dual DSI link 4K panel for display. A de-compress engine is expected in the DSI panel.

Host/eDPTx controls/configures TC358860XBG chip by using its AUX channel (I²C over AUX). TC358860XBG provides mail box register/command queue for host to control/configure/command DSI panels, too. After host writes to the command queue, TC358860XBG starts DSI “command packets” to communicate with the DSI panels.

Alternatively, an external I²C master can configure TC358860XBG via I²C bus. Command queue address can also be access via I²C bus, which means Host can use I²C to access command queue, which in turn, controls DSI panel parameters.
