Operation example
For outputting signals from all 512 channels
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 512 channels).
Clock pulse frequency = Video data rate = 50 MHz
Start pulse cycle = 564/f(CLK) = 564/50 MHz = 11.28 μs
High period of start pulse = Start pulse cycle - Start pulse’s low period min.
= 564/f(CLK) - 52/f(CLK) = 564/50 MHz - 52/50 MHz = 10.24 μs
Integration time is equal to the high period of start pulse, so it will be 10.24 μs.
tlp(ST)=1.04 µs
thp(ST)=10.24 µs

tpi(ST)=11.28 µs (line rate 88.65 kHz)

For outputting signals from 1 to 32 channels
When the clock pulse frequency is maximized (video data rate is also maximized), and the integration time is maximized (for stopping
signals at channel 32).
Clock pulse frequency = Video data rate = 50 MHz
Start pulse cycle = 84/f(CLK) = 84/50 MHz = 1.68 μs
High period of start pulse = Start pulse cycle - Start pulse’s low period min.
= 84/f(CLK) - 52/f(CLK) = 84/50 MHz - 52/50 MHz = 0.64 μs
Integration time is equal to the high period of start pulse, so it will be 0.64 μs.
tlp(ST)=1.04 µs
thp(ST)=0.64 µs

tpi(ST)=1.68 µs (line rate 595 kHz)
