Operation example
When the clock pulse frequency is maximized (video data rate is also maximized), the time of one scan is minimized, and the integra-
tion time is maximized (for outputting signals from all 2048 channels)
Clock pulse frequency = Video data rate = 10 MHz
Start pulse cycle = 2140/f(CLK) = 2140/10 MHz = 214 μs
High period of start pulse = Start pulse cycle - Start pulseâs low period min.
= 2140/f(CLK) - 92/f(CLK) = 2140/10 MHz - 92/10 MHz = 204.8 μs
Integration time is equal to the high period of start pulse + 48 cycles of clock pulses, so it will be 204.8 + 4.8 = 209.6 μs.
