(1) Related with the input maximum frequency supported by the ISP module.

(2) P = cam_pclk period in ns

(3) Maximum cycle jitter supported by cam_pclk input clock.

(4) The timing requirements are assured up to the cycle jitter and duty cycle error conditions specified.

(5) See Section 4.3.4, Processor Clocks.
