Diagonal 4.5mm (Type 1/4) CCD Image Sensor for NTSC Color Video Cameras

Description

The ICX088AK is an interline CCD solid-state image sensor suitable for NTSC color digital video cameras. This chip supports DV standard SD mode, and can drive at 13.5MHz.

High sensitivity, wide dynamic range and low dark current are achieved through the adoption of Super HAD CCD technology. In addition, high resolution is achieved through the adoption of Ye, Cy, Mg and G complementary color mosaic filters.

This chip features a field period readout system and an electronic shutter with variable charge-storage time.

The package is a 14-pin DIP (Plastic), and both top and bottom surface reference can be assured at the same time.

(3) Horizontal transfer clock waveform

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.

(4) Reset gate clock waveform

VφH

VφRG

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.
