In theory the d-phy should support 2.5gbps, but in practice it is only 1.5gbps. If CSIS to CSI (bridge) can't be made to transfer 16bit words for 12 bit raw format and if the frequency between both can go up to 500mhz, this leaves us with 4gbps (8bit x 500mhz) max bandwidth. If the above calculation is correct, this leaves us with only one option - limit the speed of the camera sensor. cheers, Petko
