Camera Sensor State Machine

Camera Sensor Power Timing

Power on Sequence

Power off Sequence

Camera Sensor Clock

PLL Block

VTPixelClock

VTPixelClock(vt_clk)Video Timing Clock, From sensor PLL

VTPixelClock = Framelengthlines x LinelengthPixelClock x FPS

OutputPixelClock

OutputPixelClock = DataratePerLane x Lane number / BitWidth

Example:

1920x1080_30fps_10bit_4lane_1.6992Gbps

OutputPixelClock = 1.6992Gbps x 4 / 10 = 679680000

MIPI Clock = DataratePerLane / 2 = 1.6992Gbps / 2 = 849.6Mbps
