SN65DSI86: MIPI DSI

GARETH OU
Guru 10625 points
Part Number: SN65DSI86

Hi


My customer has two questions

1. When MIPI DSI1 is not in use, should I float or pull up?

2. EVM line GPIO3 is the function of EDP_BL_ENABLE But REFCLK is set to 27MHz, and GPIO[3:1] requires an external resistor to set 011 But EDP_BL_ENABLE of EVM is pulled LOW directly,

and EVM is also set to 27MHz output Please also help confirm whether the GPIO needs to be pulled LOW

    Hi,

    1. Please leave unused DSI input terminals (DA*N/P, DB*N/P) unconnected or driven to LP11 state.

    2. If GPIO3 is used for EDP_BL_ENABLE, then software must program the REFCLK_FREQ, CHA_DSI_CLK_RANGE and CHB_DSI_CLK_RANGE through the I2C interface prior to issuing any DSI commands or packets to the SN65DSI86.

    Thanks
