Diagonal 11mm (Type 2/3) CCD Image Sensor for EIA B/W Video Cameras
Description
The ICX422AL is an interline CCD solid-state image
sensor suitable for EIA B/W video cameras with a
diagonal 11mm (Type 2/3) system. Compared with the
current product ICX082AL, basic characteristics such
as sensitivity and smear are improved drastically and
high saturation characteristics are realized.
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
ICX082AL and has the same drive conditions.
Features
• High sensitivity (+3.0dB compared with the ICX082AL)
• Low smear (–10.0dB compared with the ICX082AL)
• High saturation signal (+2.0dB compared with the ICX082AL)
• High resolution and Low dark current
• Excellent antiblooming characteristics
• Continuous variable-speed shutter
Device Structure
• Interline CCD image sensor
• Optical size:Diagonal 11mm (Type 2/3)
• Number of effective pixels: 768 (H) × 494 (V) approx. 380K pixels
• Total number of pixels:811 (H) × 508 (V) approx. 410K pixels

The setting value of the substrate voltage and reset gate clock voltage are indicated on the back of the
image sensor by a special code. Adjust the substrate voltage (VSUB) and reset gate clock voltage (VRGL) to
the indicated voltage. The adjustment precision is ±3%.

1) Current to each pin when 20V is applied to VDD, RD, VOUT, VSS, HIS and SUB pins, while pins that are
not tested are grounded.
2) Current to each pin when 20V is applied sequentially to V φ1, Vφ2, Vφ3 and Vφ4 pins, while pins that are
not tested are grounded. However, 20V is applied to SUB pin.
3) Current to each pin when 15V is applied sequentially to Hφ1, Hφ2, RG and VGG pins, while pins that are
not tested are grounded. However, 15V is applied to SUB pin.
4) Current to VL pin when 30V is applied to Vφ1, Vφ3, HIS, VDD, RD and VOUT pins or when, 24V is applied
to RG pin or when, 20V is applied to Vφ2, Vφ4, VGG, VSS, Hφ1 and Hφ2 pins, while VL pin is grounded.
However, GND and SUB pins are left open.
