    Hi Xiaofu,

    For 941AS, you can select the number of DSI lanes you need to use for your interface through Mode_Sel straps.

     The 941 supports 4 virtual channels on the DSI. Please refer to section "8.4.6.4.2.2 Asymmetric Splitting With DSI VC-IDs" in the datasheet.

    Yes, it's possible to use single if lower BW or dual FPD-Link for higher BW to send the video through the FPD lanes.

    We do have DP yes and we also have a newer DSI interface Ser.
    For more information about newer generation FPD-Link devices here is the marketing contact you can reach out to:
    TRANG NGUYEN (t-nguyen5@ti.com).
