E96650D99

Diagonal 4.5mm (Type 1/4) CCD Image Sensor for CCIR B/W Video Cameras

Description

The ICX087AL is an interline CCD solid-state image
sensor suitable for CCIR B/W video cameras. High
sensitivity is achieved through the adoption of HAD
(Hole-Accumulation Diode) sensors.

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

The package is a 10mm-square 14-pin DIP (Plastic).

Features

• High sensitivity and low dark current

• Horizontal register: 3.3 to 5.0V drive

• No voltage adjustment

(Reset gate and substrate bias are not adjusted.)

• Low smear

• Continuous variable-speed shutter

Device Structure

• Interline CCD image sensor

• Image size: Diagonal 4.5mm (Type 1/4)

• Number of effective pixels: 500 (H) x 582 (V) approx. 290K pixels

• Total number of pixels: 537 (H) x 597 (V) approx. 320K pixels

• Chip size: 4.47mm (H) x 3.80mm (V)

• Unit cell size: 7.3µm (H) x 4.7µm (V)

• Optical black: Horizontal (H) direction: Front 7 pixels, rear 30 pixels

Vertical (V) direction: Front 14 pixels, rear 1 pixel

• Number of dummy bits: Horizontal 16

Vertical 1 (even fields only)

• Substrate material: Silicon

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.

∗2

Do not apply a DC bias to the substrate clock pin, because a DC bias is generated within the CCD.

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
