VL setting is the VVL voltage of the vertical transfer clock waveform, or the same power supply as the VL power supply for the V driver should be used.

Do not apply a DC bias to the substrate clock and reset gate clock pins, because a DC bias is generated within the CCD.

(4) Reset gate clock waveform
VRGLH is the maximum value and VRGLL is the minimum value of the coupling waveform during the period from Point A in the above diagram until the rising edge of RG. In addition, VRGL is the average value of VRGLH and VRGLL.
VRGL = (VRGLH + VRGLL)/2
Assuming VRGH is the minimum value during the interval twh, then:
VφRG = VRGH – VRGL
Negative overshoot level during the falling edge of RG is VRGLm.
