SN65DSI86-Q1: Functionality Inquiry

Mark Philip Felipe

Part Number: SN65DSI86-Q1

Hi Team, We would like to seek you help with our customers inquiry.

Will the device support dual DSI channel inputs if the channels are not synchronized?
If only 1 channel is used, will the device support 4800 x 720 display?

I am hoping that you can assist us with the inquiry.

Thank you in advance.

Regards,

Mark

    DSI86 does not support asynchronous DSI operation when using dual DSI channel.

    For 4800x720, assuming 24Hz frequency, then pixel clock = 4800 * 720 * 24 = 82.944MHz 

    Assume 24 BPP, stream rate = 82.944 * 24 = 1.990656Gbps

    For 4 lane DSI, min DSI clock frequency = 1.990656/ (4 *2) = 248.832MHz.

    The maximum DSI Clock is the going to be 750 MHz or less, so 248MHz is within the support frequency range.

    Thanks
