Sony ICX204AK Datasheet

Description
The ICX204AK is a diagonal 6mm (Type 1/3) interline CCD solid-state image sensor with a square pixel array and 800K effective pixels. Progressive scan allows all pixels' signals to be output independently. Also, the adoption of high frame rate readout mode supports 60 frames per second. This chip features an electronic shutter with variable charge-storage time which makes it possible to realize full-frame still image without a mechanical shutter. High resolution and high color reproductivity are achieved through the use of R, G, B primary color mosaic filters. Further, high sensitivity and low dark current are achieved through the adoption of HAD (Hole-Accumulation Diode) sensors.
This chip is suitable for applications such as electronic still cameras, PC input cameras, etc.

Cross-point voltage for the Hφ1 rising side of the horizontal transfer clocks Hφ1 and Hφ2 waveforms is VCR. The overlap period for twh and twl of horizontal transfer clocks Hφ1 and Hφ2 is two.
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.
