Operation example
This example assumes that the clock pulse frequency is maximized (video data rate is also maximized), the time of one scan is mini-
mized, and the integration time is maximized
Clock pulse frequency = Video data rate = 10 MHz
Start pulse cycle = 4188/f(CLK) = 4188/10 MHz = 418.8 μs
High period of start pulse = Start pulse cycle - Start pulse’s low period min.
= 4188/f(CLK) - 92/f(CLK) = 4188/10 MHz - 92/10 MHz = 409.6 μs
Integration time is equal to the high period of start pulse + 48 cycles of clock pulses, so it will be 409.6 + 4.8 = 414.4 μs.
