ICX428ALL Diagonal 8mm (Type 1/2) CCD Image Sensor for EIA B/W Video Cameras Description The ICX428ALL is an interline CCD solid-state image sensor suitable for EIA B/W video cameras with a diagonal 8mm (Type 1/2) system. Basic characteristics such as sensitivity, smear, dynamic range and S/N are improved drastically through the adoption of EXview HAD CCDTM technology. This chip features a field period readout system and an electronic shutter with variable charge-storage time. This chip is compatible with the pins of the ICX248AL and has the same drive conditions. EXview HAD CCD TM has differrent spectral characteristics from the curreent CCD. 20 pin DIP (Cer-DIP) Pin 1 2 V Features • High sensitivity • Low smear 3 • High D range 40 H Pin 11 • High S/N • High resolution and low dark current Optical black position • Excellent antiblooming characteristics (Top View) • Continuous variable-speed shutter • Substrate bias: Adjustment free (external adjustment also possible with 6 to 14V) • Reset gate pulse: 5Vp-p adjustment free (drive also possible with 0 to 9V) • Horizontal register: 5V drive 12 Device Structure • Interline CCD image sensor • Optical size: Diagonal 8mm (Type 1/2) • Number of effective pixels: 768 (H) × 494 (V) approx. 380K pixels • Total number of pixels: 811 (H) × 508 (V) approx. 410K pixels • Chip size: 7.40mm (H) × 5.95mm (V) • Unit cell size: 8.4µm (H) × 9.8µm (V) • Optical black: Horizontal (H) direction: Front 3 pixels, rear 40 pixels Vertical (V) direction: Front 12 pixels, rear 2 pixels • Number of dummy bits: Horizontal 22 Vertical 1 (even fields only) • Substrate material: Silicon TM ∗ EXview HAD CCD is a trademark of Sony Corporation.
