The shift register starts operation at the rising edge of CLK immediately after ST goes low. The integration time can be changed by changing the ratio of the high and low periods of ST. If the first TRG pulse after ST goes low is counted as the first pulse, the Video signal should be acquired at the rising edge of the 89th TRG pulse. 7 Micro-spectrometer C12880MA Operation example This is an operating example when the clock pulse frequency is set to maximum (video data rate is also set to maximum), the time per scan to minimum, and the integration time to maximum. ∙ Clock pulse frequency [f(CLK)] = Video data rate = 5 MHz ∙ Start pulse cycle [tpi(ST)] = 381/f(CLK) = 381/5 MHz = 76.2 μs ∙ Low period of start pulse min. [tlp(ST)] = 375/f(CLK) = 375/5 MHz = 75 μs ∙ High period of start pulse [thp(ST)] = Start pulse cycle [tpi(ST)] - Low period of start pulse min. [tlp(ST)] = 76.2 μs - 75 μs = 1.2 μs thp(ST)=1.2 μs tlp(ST)=75 μs ST tpi(ST)=76.2 μs KACCC0772EA Integration time is equal to the high period of start pulse + 48 cycles of clock pulses, so it will be 1.2 μs + 9.6 μs = 10.8 μs.
