For a MIPI interface with 600Mb/s per lane, 4 lanes, single pixel mode design, processing YUV420 8-bit data, the minimum required video clock is (600*4)/(1*8) or higher, where 8 is the number of bits in one 8-bit YUV420 pixel.
video_aclk1(Mhz) = 600*4/(4*8) = 75Mhz
video_aclk2(Mhz) = 600*4/(1*8) = 300Mhz
The final video clock is:
video_aclk(Mhz) = max{75Mhz,300Mhz} = 300Mhz
Note: Due to the internal data path architecture of the pixel processing the minimum supported data type for line rates greater than 1500 Mb/s is RAW8. RAW6 and RAW7 data types are not supported for line rates greater than 1500 Mb/s.
