In this figure, charge is transported to the left output buffer (normal readout) by moving it from C1 to C2 to C3 etc. By exchanging the timing of C1 and C2, charge will be transported to the right output buffer (mirrored readout).

Frame Transfer (FT): Charge Pump (CP): a measure to reduce dark current due to interface states. For details see figure 3 "Line and pixel timing diagrams". Hustle: moving the charge packets of one line from storage to the output register. For details see figure 3 "Line and pixel timing diagrams". Linetime: the C-clocks shift charge packets one-by-one to the selected output buffer. For details see figure 3 "Line and pixel timing diagrams". Black-Level Clamp (BLC): the video processing clamps the black lines to determine its output zero-level. Figure 4: Frame Timing Diagrams Frame Timing Frame Shift Timing Tp=1/(36MHz=27.8ns
