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 = 2548/f(CLK) = 2548/10 MHz = 254.8 μs
High period of start pulse = Start pulse cycle - Start pulse’s low period min.
= 2548/f(CLK) - 64/f(CLK) = 2548/10 MHz - 64/10 MHz = 248.4 μs
Integration time is equal to the high period of start pulse + 34 cycles of clock pulses, so it will be 248.4 + 3.4 = 251.8 μs.
